Javier drove 299.6 miles on 14 gallons of gas. At this rate, how many miles can he travel on 25.5
gallons?

545.7 miles.

Step-by-step explanation:

299.6/14 = 21.4

1 gallon will last 21.4 miles

Multiply 21.4 by 25.5

21.4*25.5 = 545.7

Therefore, Javier can travel 545.7 miles on 25.5 gallons.

$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)
