- 275 + 125x = 1850 - 100x
- 125x + 100x = 1850 - 275
- 225x = 1575
- x = 1575 / 225
- x = 7

Answer:
Step-by-step explanation:
if 124.50 represents 100%
how much x represents 6% ?
cross multiply
x= 124.50*6/100= 7.47
$7.47 > $5.95 so it will pay $7.47 in shiping
Adults = 9
Children = 2
Let x be the number of adults.
11-x is the number of children.
22x + 15(11-x) = 228
22x + 165 - 15x = 228
22x - 15x = 228 - 165
7x = 63
7x / 7 = 63 / 7
x = 9 number of adults.
11 - x = 11 - 9 = 2 number of children.
To check:
22x + 15(11-x) = 228
22(9) + 15(11-9) = 228
198 + 30 = 228
228 = 228
(not my answer btw)
