Sadie ordered a pizza with a fixed delivery fee of 3.50. The total cost (c) is determined by the price of the pizza (p) plus the delivery fee, using the rule: c = p + 3.50. If the price of the pizza is 12.00$, what is the total cost?
Explanation
Substitute the price p = 12.00 into the given equation: c = 12.00 + 3.50 = 15.50.
The table below shows the relationship between the number of hours a handyman works (h) and the total amount he charges in dollars (d). Which equation represents the relationship between the number of hours (h) and the total charge (d)?
Explanation
The ratio of charge to hours is constant: 50/2 = 25, 75/3 = 25, and 125/5 = 25. Therefore, the equation is d = 25h.
The table below shows the total cost (c) of renting a canoe for a certain number of hours (h). The cost includes a fixed one-time rental fee plus an hourly rate. Which two-step equation represents the total cost of renting a canoe for h hours?
Explanation
The hourly rate is the change in cost: 27 - 16 = 11. The fixed fee is the cost at 1 hour minus the hourly rate: 16 - 11 = 5. Thus, c = 11h + 5.
The graph shows the total cost c of buying one large bucket of popcorn and d large drinks at a movie theater. Which equation correctly represents the relationship shown in the graph?
Explanation
The graph starts at c=4 (the popcorn bucket). When drinks d=1, cost c=12. The slope is 12 - 4 = 8. The equation is c = 8d + 4.
A school sells tickets to a play for 8$ each. The ticket company adds a 2.50$ processing fee to the total order. Which equation can be used to find the total cost (c) for buying (t) tickets?
Explanation
The total cost includes 8 dollars per ticket plus a one-time fee of 2.50 dollars, giving the equation c = 8t + 2.50.
A store charges 1.70$ for a fountain soft drink. The total cost c of d soft drinks is calculated using the rule 1.7d. Using the table below, what is the missing total cost when 3 soft drinks are purchased?
Mr. Hamilton has 144 pencils to give to his students. The number of pencils p each student will receive is equal to 144 divided by s, the number of students. Which of the following numbers should be entered into the input column (top to bottom) in order to complete the table?
Explanation
To find s, solve 144/s = p. For p=12, s=12; for p=9, s=16; for p=6, s=24.
Heath is selling magazine subscriptions. He earns 10$ for every subscription sold. Use s to represent the number sold and t for total earnings. Which of the following equations can be used to find Heath's total earnings t given s subscriptions sold?
Explanation
Since Heath earns 10 dollars for each subscription, his total earnings t are the number of subscriptions s multiplied by 10.
A car rental company uses the equation c = 15h + 20 to determine the total cost c in dollars for renting a car for h hours. If a customer rents a car for 4 hours, what is the total cost they must pay?
Explanation
Substitute h=4 into the equation: c = 15(4) + 20 = 60 + 20 = 80.
