Answer 2

Jamie bought a hand cover fiction book with $32.99 price.
She has a coupon that has a 15% off.
The store offers 20% off
x= how much will she save?

=> 20% = 20/100
=> .20
=> 15% = 15/100
=> .15
=> .20 + .15
=> .35

=> The amount is 32.99, multiply this by .35
=>  32.99 x .35
=>  11.5465 – She saved $11.55
=>  32.99 – 11.5465
=> 21.4435 – She only paid 21.4435 for her hand cover fiction book that she bought.
