Mr. and Mrs. McPherson have to renew their rent by the end of the year. They agreed that Mrs. McPherson would raise 30% of the money. If their rent is $1200 per year, how much does Mr. McPherson need to raise to complete the rent?
Stream of thoughts:
840
30% of $1200 is (30 / 100) * $1200 = $360.

Mrs.

McPherson will pay $360 leaving $1200 - $360 = $840 which Mr.

McPherson will have to raise.

.

The answer is 840
