Give the step-by-step reasoning process and then the final answer. 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?
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 final answer: 840.
