Question

Quizplus · Accepted Answer

If Larry spends all his $800 monthly income on pizza and milk, we can set up an equation:
$800 = $4 (number of pizza slices) + $2 (number of quarts of milk)
Let's solve for the number of pizza slices:
$800 = $4x + $2y
We don't know how many quarts of milk Larry buys, but we can assume he buys at least 1 quart. If he buys 1 quart, that's $2, leaving $798 for pizza. Each pizza slice costs $4, so he can buy:
$798 / $4 per slice = 199.5 slices
Since Larry can't buy half a slice, we round down to 199. Therefore, Larry's real monthly income in terms of pizza is 199 slices, which is represented by choice (C).
