3. the three salespeople for a local advertising firm are lola, ahmed, and tommy. lola sold $2030 in ads, ahmed sold $1540, and tommy sold $1800.
(a) what fraction of the total sales did each salesperson sell?
(b) a $100 bonus was awarded to the three salespeople, which they had to share. it was awarded so that each salesperson received the same fraction of $100 as he or she sold of the total sales. how much did each person receive? round to the nearest whole cent.

First compute the total sales

Total sales = 2030 + 1540 + 1800 = 5370

The fraction of each are:

Lola = 2030 / 5370 = 0.378

Ahmed = 1540 / 5370 = 0.287

Tommy = 1800 / 5370 = 0.335

Bonus they get

Lola = 100 x 0.378 = $37.8

Ahmed = 100 x 0.287 = $28.7

Tommy  = 100 x 0.335 = $33.5

$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)
