The current i   in an electrical conductor is inversely proportional to its resistance r . if the current is 1 /4   ampere when the resistance is 100   ohms, what is the current when the resistance is 150   ohms? keep your answer in rational form and omit units.

$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)
