Weren't there more instructions?  Please, share everything about each problem you post here.

Use the compound amount formula:  A = P(1 + r/n)^(nt).

Here we have

A = $1500(1 + 0.023/2)^(2t), where t is the number of years.

well there are two answers for that.

1: you need 120 ones then that will equal up to 120.

2: you could also do one 100 and 2 tens.

those are the answers that i have thought of.

total amount to be paid = $19.5

step-by-step explanation:

given ,

original price = $25.99

discount = 25%

discount amount = 25% of original price

discount amount = 25/100   * 25.99

discount amount = $6.49

hence , the total amount to be paid = original price - discount amount

                                                            = $25.99 - $6.49

                                                            =$19.5

total amount to be paid = $19.5
