Question

1. Rita had enough money to buy 15 books
for 30 each. If the price of each book
increases resulting in a total cost increase of
45, how many books can she buy now?
How much money will be left with her?​

Answer 1

Answer:

Step-by-step explanation:

Because I am not sure about the questions I will do both my thinking.

Amount she have = 15*30 = 450

1st:

New cost = 30+45 = 75

Unknown*75 = 450

     Unknown = 450/75

                       = 6

Therefore she can buy 6 books

2nd:

New cost = 45

Unknown*45 = 450

     Unknown = 450/45

                       = 10

Therefore she can buy 10 books

Hope that helped!
