I can’t find the answer. Are you sure this is the whole question?
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
7.91 = 8 21.9 = 22
8 + 22 = 30
18 = x times 8
to solve this do 8 dive by 8 than cross it out than 18 dive by 8 which is 2.25 i think this is the answer
