Question

Marina works in a shop.
She earns $ 4.5 per hour.
She also earns a bonus of 12% of the value of the items she sells in a week

1) In the second week of May, Marina worked for 30 hours and earned a
total of $ 351.
Calculate the value of the items she sold that week
2) In the third week of May, as the bonus she earned 15% more than the
bonus of the first week.
Calculate the bonus she earned in the third week of May.

Answer 1

sol: 1) marina earns without bonus = 30×4.5

= $135

marina earns with bonus = $351

bonus = 351-135

bonus = 216

NOW,

let the value of the items = x

12 percent of the value of items = 216

X × 12/100 = 216

X = 216×100/12

X = 1800
