Question

Michelle plans on raising $80 for her softball team. To raise the money, she is selling team shirts for $10 each.

Answer 1

Given:

Michelle plans on raising $80.

Selling price of each shirt = $10

So far she has raised $20.

To find:

The number of more shirts she needs to sell.

Solution:

Let x be the number of more shirts she needs to sell.

Selling price of one shirt = $10

Selling price of x shirt = $10x

Total raising amount = $(10x + 20)

Michelle plans on raising $80. So,

$10x+20=80$

Subtract both sides by 20.

$10x=80-20$

$10x=60$

Divide both sides by 10.

$x=\dfrac{60}{10}$

$x=6$

So, the required equation is $10x+20=80$

Therefore, the correct option is A.
