Can someone help me explain it

110.40

Step-by-step explanation:

First find the discount

120 * 20%

120*.2 = 24

Subtract this from 120

120-24

96

Now find the tip

96* 15%

96*.15

14.4

Add this to the 96

96+14.4

110.40

$110.40

Step-by-step explanation:

The total is $120 and since there a coupon we need to subtract 20%

20% as a decimal is 0.2

When you do 0.2 multiplied by 120 you would get 24

After that you subtract $24 and get $96

15% as a decimal is 0.15

0.15 multiplied by 96 is 14.4

94 + 14.4 = 110.4

answer: two high and two low
