2. a)
The charge of electricity from 0-50 units is at the rate of Rs 7.30 per unit and Rs 8.60
per unit from 51-150 units. If the total normal charge of electricity was Rs 795, how
many units of electricity was consumed?

$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)

do you mean add both of the equations together

because if you do the answer is 10x-5
