Marcy split her income from last week equally between paying her student loans, rent, and savings. She put $300 in savings. How much did Marcy earn last week?

?/3 =

Marcy earned $___ last week

x/3 == 300

Marcy earned $900 last week.

Step-by-step explanation:

For this problem let's consider that 3 equal parts, or "split her income from last week equally" is 3 parts of her entire paycheck.

So she put $300 into savings which is x/3, if we let x represent the amount in dollars of her entire paycheck.

Then we can say the following:

If x / 3 == $300, then x == $900.

x / 3 == 300

( x / 3) * 3 == 300 * 3

( x * 3 / 3 ) == 300 * 3

x == 300 * 3

x == 900

So you can say the following:

x/3 == 300

Marcy earned $900 last week.
