EXAMPLE - Your family budgets $160 to spend on fuel for a trip. How many times can they fill the car’s gas tank if it cost $25 each time?

There are 461 students and 20 teachers taking buses on a trip to a museum. Each bus can seat a maximum of 52. What is the least number of buses needed for the trip?

A donut shop charges $ 0.70 for each donut and $ 0.30 for a carryout box. Shirley has $5.00 to spend. At most, how many donuts can she buy if she wants them in a carry out box?

In order to be admitted for a certain ride at an amusement park, a child must be greater than or equal to 36 inches tall and less than 48 inches tall. Graph the possible heights for riders.

Herman decides to take up golf. His golf club membership will cost $450 for the season and he will be charged $18 for each round of golf that he plays. Herman has decided not to spend more than $1000 on golf for the season. a.) Write an inequality that describes the relationship between the maximum amount Herman wants to spend and the total golf costs for the season. b.) Solve the inequality to determine the maximum number of rounds of golf he can play yet not exceed his $1000 limit.

Ashley has a $20 bill and needs to buy three Hallmark Blossom birthday cards at $2.55 each. With the left over money she would like to buy as many Paw Note thank you cards as possible.
