We know that they EACH bought a hockey puck($17) and 2 shirts
Half of 214 is 107. So they had to have spent 107 separately

2s + 17 = 107
- 17 -17
2s= 90. DIVIDE by 2
s = 45
Answer:
The ratio of boys to girls to 5:7
Let the number of boys be 5x
Let the number of girls be 7x
5x = 30
x = 6

and number of girls 7 x 6 = 42
we have given for 12 ounces is $40.80.
we need to find the rate for unit ounce.
we know that
.
so one ounce cost about $3.4.
