Question

Ritu  earns R s 680 in commission and is paid R s 10.25 per hour. Karina earns R s
410 in commissions and is paid R s 12.50 per hour. What will you find if you solve
for x in the equation 10.25x + 680 = 12.5x + 480

hintHint:

To solve the equation, group terms with the same coefficient on one side and numbers on                      the other side.

The correct answer is: Hence, the x = 88.88.


    Answer:
    • Step by step explanation:
    ○    Given:

                    10.25x + 680 = 12.5x + 480
    ○    Step 1:
    ○    Solve the equation.
    ○    Group the like terms

                   10.25x + 680 = 12.5x + 480

                    rightwards double arrow680 - 480 = 12.5x - 10.25x

                    rightwards double arrow200 = 2.25x
    ○    Step 2:
    ○    Divide both side with 2.25

                    not stretchy rightwards double arrow fraction numerator 200 over denominator 2.25 end fraction equals fraction numerator 2.25 x over denominator 2.25 end fraction

                    rightwards double arrow88.88 = x

    • Final Answer:
    Hence, the x = 88.88.
