Question

Pipers Pizza shop used 18% more cheese this month than last month, due to having a discount on the extra chesse toppings. If the pizza shop used 150 pounds of cheese last month how much did it use this month

Answer 1

177 pounds

Explanation:

Create an equation to represent the system.

Since it's 18% more than what was used last month an equation can be written such as the one below:

(118%)( last month's cheese ) = this month's cheese

Convert the percentages into decimals by moving the decimal place at the end of 118.00 two places to the left

118% = 1.18

( 1.18 )( last month's cheese ) = this month's cheese

Next, plug in the number for last month's cheese

( 1.18 )( 150 pounds) =

177 pounds
