Marco is initially paid $75 per week and the 2.5 more each week than the previous week

Answer 1

Hello, Ricardo. This question is essentially telling you that Marco gets paid $75 per week and the following week, his pay will increase by a rate of 2.5 times his current rate. So, if you were asked how much Marco will make in week 2, you would multiple 75 times 2.5 which would give you 187.5 (75+75+37.5). Then if you are asked how much he makes in week 3, you would take 187.5+187.5+93.75 = 468.75.
