Answer:
45
Step-by step
What do we already know about the equation?
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
So we make the equation and let s represent shirts
2s + 17 = 107
- 17 -17
2s= 90. DIVIDE by 2
s = 45
2 3/5 is 2.6 as a mixed fraction
The answer is C
adult: x
student: y
x+y=120
6x+4y=560
X+6 = 3x - 12 (right?)
6 = 2x-12
18 = 2x
9 = x
4x-15 = 2x+3
2x-15 = 3
2x = 18
x = 9
Basically, x = 9
Hmmmm closest I can get to this answer is 6 or 7. The numbers don't add up and it's probably why you haven't received an answer. If you do this math:
13small candles multiplied by 10.98 = 142.74
7large candles multiplied by 27.98 = 195.86
142.74+195.86 = 338.60 which is OVER the total received.
7+13=20 candles
14small candles multiplied by 10.98 = 153.72
6 large candles multiplied by 27.98 = 167.88
153.72+167.88 = 321.60 which is UNDER the total received
Can't go any lower or higher because it's even lower or higher.
6+14=20 candles
So I wouldn't really know what to say. This isn't adding up.
