Question

2. Nate ordered several t-shirts for $7.90 each and paid $2 for shipping. If

Nate spent a total of $160, how many t-shirts did he order?

Answer 1

7.90x + 2 = 160

He bought 20 shirts.

Explanation:

We want to create an equation, with x representing the number of shirts he bought.

We know it will equal $160, because he paid $160;

= 160

$2 is the flat rate, so we need to add it;

2+ __ = 160

$7.90 is the cost per shirt, so we multiply it by x and add it;

2 + 7.90x = 160

7.90x = 160-2

7.90x = 158

x = 20 shirts
