Victor

pays $1200 rent. If his monthly salary is $3800, what percent of his

monthly salary is his rent? Round to the nearest tenth of a percent.

We know that $1200 is x percent of $3800, what can be written down as:

1200 = x% * 3800

1200 = x/100 * 3800

1200 = x/1 * 38

1200 = x * 38

1200 = 38x / : 38 (both sides)

x = 31,57894736842105

x ≈ 31,6 (after rounding to the nearest tenth)

So Victor pays about 31,6% of his monthly salary.
