Question

Dave has $11 to spend on an $8 book and two birthday cards (c) for his friends. How much can he spend on each card if he buys the same card for each friend? WHAT IS THE INEQUALITY

Answer 1

Dave has $11 and he buys a book for $8 but he spends an equal amount of money on 2 cards. Let's model this problem with an inequality.

x = $ spent on one card.

2x + $8 ≤ $11

Let's subtract $8 from both sides.

2x ≤ $3

Divide both sides by 2

x ≤ $1.5

Dave can spend at most $1.5 on each card.
