The Central Texas drought causes the water level of area lakes to exponentially decay by a rate of
20% per year. If Lake Travis had 300 billion
gallons of water in 2010, how many billions of
gallons are left three years later?
First, complete the equation:
Remaining Amount = 300(1 - [?]

$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)
