Question

At her local craft store, Adrienne bought 4 small picture frames that cost $2.95 apiece and 5 cans of poster paint that cost $1.75 apiece. When the cashier informed her that all purchases of 10 items or more would be discounted by 10%, she decided to buy an art eraser for $0.45. How much money did this last purchase end up saving her
1. $1.65 2. $2.25 3. $3.75 4. $18.90 5. $20.55

anonymous · Answer

Cost of 9 items=$20.55
Price of ten items=$21.00
Price after discount=21.00-(0.1*21.00)=$18.9
Money saved=21.00-18.9-0.45=1.65
(I have subtracted 0.45 as she does not intend to spend it)
