Anna11 [10]

Answer:

Increase (A)

Step-by-step explanation:

If the common ratio is greater than 1, that means the y-value increases as the x-value increases.

If the common ratio is 1, that means the y-value stays the same as the x-value increases.

If the common ratio is between 0 and 1, that means the y-value decreases and approaches 0 ad the x-value increases.

Because the common ratio is greater than 1, the answer is A, increases

Joel earns $1,500 per month. If he spends $375 on rent each month, what percent of his income does he spend on rent?
cricket20 [7]
First, we must express the ratio of rent to Joel's total earning. 375 out of 1500 in its simplest form is 1/4. To express a value in percentage, we must multiply it to 100. Thus, for this case, we have 1/4 x 100 = 25% That means, out of a total of 100%, Joel spends 25%<span>of his income on rent.</span>
