Matthew is paid $8.50 for each acre he mows on his grandparent's estate. He mows 50% of an acre in 3/5 of an hour.

Question

At the rate, how much will Mathew be paid for two hours of moving? Round to the nearest cent.

exact answer =$19.83

rounded answer = $20

Step-by-step explanation:

3/5 = 0.6, so in 0.6 hours he can do 50% so in 2 hours that has 3 0.6 so 150% and the remaining time is 0.2 hours thats 1/3 of 0.6 so just divide 50% by 3 you'll get around 16.7% so in 2 hours he finished 166.7%

16.7% = 1/3 of 50% = 8.50 = 8.50/3 = 2.83

so 8.50 + 8.50 + 2.83 =

$19.83

the answer will be b x² +x-1
