Answer:
A
Step-by-step explanation:
Juan’s lunch would have costed less if he paid separately. his lunch is 5.25
the bill 37.20
37.20 / 5
$7.44 each kid
7.44 - 5.25 = 2.19
$2.19 less if he paid separately
95% * x = 95
95/100 * x = 95
0,95 * x = 95
0,95x = 95 / : 0,95
x = 100
To decrease something at 100% by 7% is:
100% - 7% = 93%
You multiply the original value by 0.93 to decrease it from it's original value by 7%
