They will need to sell 16 T-shirts to reach their goal

Step-by-step explanation:

Let us solve the question

∵ The school store is selling notebooks for $1.50 and T-shirts for$10.00

∴ The price of each notebook = 1.50 dollars

∴ The price of each T-shirt = 10.00 dollars

∵ They have sold 60 notebooks

∴ The number of notebooks sold = 60

∵ They have a goal of raising \$250

∴ The total money they want to earn = 250 dollars

Assume that they will sell x T-shirt to reach their goal

Multiply the no. of notebooks by the price of each and the no. of T-shirts by the price of each, then add the two products and equate the sum by 250

1.50 (60) + 10.00 (x) = 250

∴ 90 + 10x = 250

→ Subtract 90 from both sides

∵ 90 – 90 + 10x = 250 – 90

∴ 10x = 160

→ Divide both sides by 10 to find x

x = 16

∴ The number of T-shirts = 16

They will need to sell 16 T-shirts to reach their goal
