    Answer:

    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
