4. 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

Step-by-step explanation:

total money rita had = 15× 30 = 450 rupees

total cost= 45 rupees

increase in cost of per book = 45/ 15 = 3

new cost per book = 33 rupees

total book she bought = 450/ 35= 13

money left with her = 450-33×13=21
