Ebony's bank balance first reached $400 on Day 4. The last day her balance was $400 was Day 8. (a) Determine B(5), B(6), and B(7). Explain how you determined these amounts.

$53.50

step-by-step explanation:

you have to subtract the amount of money chuck earned ($72.50) by the cost of the gas for the mower ($11.25) and the new string for the trimmer he bought ($7.75).

72.50-11.25=61.25

and then subtract $61.25 by the second thing he bought (the new string for the trimmer)

61.25-7.75=53.5

so in total it's $53.50 (53 dollars and 50 cents)

the answer is 844

step-by-step explanation:

it is 844 because if you add 836.50 + 7.5 you will get 844
