Question

Carlos has at most $40 to spend on food for a barbeque. He wants to buy hot dogs and hamburgers and then

Alls for each. Carlos has already spent $31.50 on the hot dogs and hamburgers. Let r represent the amount of
noney that Carlos can spend on the rolls.
Write and solve an inequality.

Answer 1

$8.50

Explanation:

I don't know what Alls are, but if Carlos insists, we can calculate how much he can spend on Alls with the expression:

($31.50) + r
`\leq` $40

This says the sum of what Carlos has already spent (hot dogs and hamburgers) plus the amount he spends on Alls (rolls?), r, must be equal to or less than the $40 he has allowed himself to spend.

($31.50) + r
`\leq` $40

r
`\leq` $40 - $31.50

r
`\leq` $8.50
