Question

When Lucy was one month old her grandparents put $25
into a safety deposit box. The next month they put $30,
followed by $35 the month after that. They continued
adding money like this, each month adding $5 more than
the previous month. Her grandparents told her they would
continue doing so until her 18th birthday, at which point
she could use the money to attend college.
a) How much was added into the deposit box on
Lucy’s 10th birthday?
b) How much was added for the final deposit on
Lucy’s 18th birthday?

And

Luke’s father has told him that if Luke walks around the
neighborhood for a whole day to pick up trash then he will
pay him for doing so. He will pay Luke $0.20 for the first
piece and increase the pay by 5% for each piece after that.
This way Luke will get paid more for the pieces that are
harder to find. (round answers to the nearest penny)
a) How much money will Luke be paid for his 100th
piece of trash?
b) If Luke picks up 150 pieces total, then what is the
payment he receives for that final piece?

And

Answer 1

Answer: 95$

Step-by-step explanation:

First you have to add 25 +30 and then you get 55

So 55 dollars was added to Lucy deposit box on her 10th birthday

Now for her 18 birthday

You have to do 55+35and you get 90 then add 90+5 which is 95

So there was 95 dollars added in her deposit box on her 18 birthday
