I need steps on how to do this pls.

Step-by-step explanation:

Find the numerical amount of each percent first, by using proportions.

So, 20% of 562 is: x/562=20/100 (112.4)

Solve that proportion and then subtract the answer from $562(449.6). This represents the total he would have to pay without tax and the 2% off.

Next create a proportion for the 6% sales tax: x/449.6=6/100(about $27)

Add that to the remaining amount after subtracting his contractors discount.($476.6)

Next, make a proportion for the 2% discount he receives from the credit card company: x/476.6=2/100($9.53) Subtract that from 476.6: $467.07(answer)
