Answer 1

a) $10.45 (that's what paypal charges, not the entire cost in total --- I'll assume you are smart enough to get the total cost.)

To find the percent of something, use is over of.

is/of = %/100, meaning you have to cross-multiply.

for this problem, you will use the equation:

x/350 = 2.9/100

2.9*350/100 = x

1015/100 = 10.15

Then you add the extra 30 cents

wich brings you to the ANSWER----> 10.45$

b) It's hard to understand the second question, because it is worded weirdly. I think you are saying they get 10% of the difference reimbursed... but you could be saying the difference + 10% of the difference... You should really make it clearer. I think it's $2.20

Same thing, you use is/of equation.

first, you subtract 98 from 120, because that would be your difference.

120-98 = 22

x/22 = 10/100

10*22/100 = x

220/100 = 2.2 = $2.20

If you are saying you get back the difference PLUS 10% of the difference, your answer would be $24.20.
