Explanation


30 apples at 40 cents apiece cost $12. Buying 30 apples at 3 per dollar would cost $10. Therefore, the sale price is $2 less than the normal price.

E. $3


At regular price, 30 apples cost 30 x 0.40 = 12 dollars.

At the sale price, 30 apples cost 30 x 1/3 = 10 dollars.

So at the sale price, a total of 2 dollars is saved.

Answer: C

I figured the savings of the 3rd one by realizing that you save $0.20 when you buy 3 at the sale price and multiplying the $0.20 by 10 to equate to the 30 apples for a total savings of $2. Will that strategy always work or did the numbers just work out well in this case?

C. $2
D. $2.50
E. $3


REGULAR PRICE
At $0.40 apiece, the cost of 30 apples = (30)($0.40) = $12.00

REDUCED PRICE
At $1.00 per THREE apples, each apple costs $1.00/3
So, the cost of 30 apples = (30)($1.00/3) = $10.00

$12.00 - $10.00 = $2.00

Answer: C

Cheers,
Brent
