Question

How much did Briana save by purchasing a backpack that costs $45 with a sales promotion of 20% off instead of a backpack that cost $42 with a sales promotion of 10% off?

Answer 1

Answer:

Briana saved $1.80.

Step-by-step explanation:

When the sales promotion is 20% off.

Cost price is $45

Amount after discount is = $45-(0.20\times45)=36$ dollars

When the sales promotion is 10% off.

Cost price is $42

Amount after discount is = $42-(0.10\times42)=37.80$ dollars

Hence, Briana saved $37.80-36=1.80$ dollars

Answer 2

45x.20=9
42x.10=4.2
9-4.2=$4.80
