Question

Manny and Luis spent the same amount of money on school supplies. Manny bought a binder for $5 and spiral notebooks for $1 each. Luis bought a binder for $8 and spiral notebooks for $0.75 each. How many spiral notebooks did each boy purchase if they each bought the same number of spiral notebooks?

Answer 1

Each boy purchased 12 spiral notebooks.

Step-by-step explanation:

In order to find out how many spiral notebooks each boy purchased, we need to set up an equation using the given information:

Let x be the number of spiral notebooks bought by each boy.

Manny: Cost = $5 + $1 * x

Luis: Cost = $8 + $0.75 * x

Since Manny and Luis spent the same amount of money on school supplies, we can set the two equations equal to each other:

$5 + $1 * x = $8 + $0.75 * x

By subtracting $0.75 * x from both sides of the equation, we get:

$5 + $0.25 * x = $8

By subtracting $5 from both sides of the equation, we get:

$0.25 * x = $3

Dividing both sides of the equation by $0.25, we get:

x = 12

Therefore, each boy purchased 12 spiral notebooks.
