GH¢ 338\text{GH¢ 338}

Step-by-step solution

5 steps

Here's the solution for question 7(a):

  1. Identify the given formula for the total cost CC.

    The total cost CC is given by the formula:

    C=0.03pc+50C = 0.03pc + 50

    where pp is the number of pages and cc is the number of copies.

  2. Identify the given values for pp and cc.

    We are given:
    p=80p = 80 pages
    c=120c = 120 copies

  3. Substitute the values of pp and cc into the formula.

    C=0.03×(80)×(120)+50C = 0.03 \times (80) \times (120) + 50

  4. Perform the multiplication.

    C=0.03×9600+50C = 0.03 \times 9600 + 50 C=288+50C = 288 + 50

  5. Perform the addition to find the total cost.

    C=338C = 338

    The total cost is 338 GH¢.

    The total cost when p=80p = 80 pages and c=120c = 120 copies is GH¢ 338\boxed{\text{GH¢ 338}}.
