    Answer:

    0.972x

    Step-by-step explanation:

    x – 0.1x + 0.08(0.9x)

    Converting percentages to decimals has you divide the percentage by 100.

    So our first equation is full price minus a tenth of that price, leaves you with nine tenths, right? Then we multiply that nine tenths by 8 percent, which is 8 hundredths.

    0.9x + 0.072x = 0.972x
