Answer:
Explanation:
Q1)
A toffee costs $0.15 + $0.10 = $0.25
If you buy 15 candies, it will cost you 15* $0.15 = $2.25
If you buy 12 toffees, it will cost you 12* $0.25 = $3.00
So buying 15 candies is $3.00 - $2.25 = $0.75 cheaper than buying 12 toffees.
Q2)
The original price of two tennis rackets is $120 x 2 = $240
The original price of three cans of tennis balls is $15 x 3 = $45
So the original price of two tennis rackets and three cans of balls is $240 + $45 = $285
By buying two tennis rackets and three cans of balls at the sale price of $255, you save $285 - $255 = $30 off the original price.
