Susie makes a base monthly salary of $4500. She also earns 14% commission on all her sales. She sold $12 000 worth of items this month. (a) Calculate the amount of money Susie earned in commissions. [2]​

$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)

b is the right answer
