7.5× 18.5=138.75 first week
7.5×20=$150 second week
total earnings 138.75+150=$288.75
She did multiply correctly 7.5 ×18.5 but got the wrong figure resulting in in lower pay and she did not multiply the 7.5 × 20 in the seond week. She shouldve added the week one and two wages to get her pay for 2 weeks
