Gina is having a party and wants to spend less than $505. She has already spent $400. The only item left on her list is pizzas, which cost $15 each. How many pizzas, x, can she purchase and stay under her budget?
A.
x < 34
B.
x < 90
C.
x < 27
D.
x < 7

She can buy 7 pizzas. Before I get into the math im pretty sure you misused the < symbol (=) but whatever. Firstly you subtract 400 from 505 (505 - 400) which equals 105. Now all you need to do is divide 105 by each number in an answer choice to get your answer. After completing you will find that D is correct because 7 x 15 = 105.
