35 multiplied by .20 is 7. so 35 minus 7 is 28. 28 times .06 is 1.68. 28 plus 1.68 is $29.68.
<h2>
Step-by-step explanation:</h2>
We need to think, 28 / 42 = x / 54.
We need to do a proportion for this problem!
First, line up both fractions, then put a equal sign between both fractions.
28 / 42 = x / 54.
We multiply in a diagonal and then we divide by the one without a diagonal.
28 and 54 are a diagonal.
We multiply both numbers!
54 x 28 = 1,512.
Then, we divide by 42.
1,512 / 42 = 36.
Therefore, x = 36.
