Answer:
2 outfits
Step-by-step explanation:
first you have the total amount of money he has.
next subtract the amount of money he spends on the new bicycle
500-273.98=226.02
next find the total cost of the 3 bicycle reflectors
7.23 times 3 = 21.69
Subtract that total from the remaining amount of money left
226.02 - 21.69 = 204.33
Then subtract the helmet from the remaining money
204.33 - 42.36 = 161.97
now divide the remaining money by 78.12 to find out how many outfits he can buy
161.97 / 78.12 = around 2.07
So the answer is he can only buy 2 outfits with the remaining money
(you can not buy 2.07 outfits)
hope this helps and was what you were looking for
2x+4y=0
3x+y=10
So what we want to do is get y onto one side by itself using whatever equation you like.
So I'm taking 2x+4y=0 and subtracting 4y from both sides
So we end up with
2x=4y
Divide both sides by four
2/4x is 1/2 x
So we get 1/2x=y
Take this and plug it into the other equation
3x+y=10
3x+1/2x=10
Add your like terms
3 1/2x=10
Putting 3 1/2 as a mixed number we get 7/2
So..
7/2x=10
Multiply by the opposite of 7/2 on both sides
Which is 2/7 this will cancel out the left side.
So we end up with
X= 10•2/7
X=20/7
Which is 2 and 6/7 as a mixed number.
I think your asking how much the school will have left over. If so:
125 ( not including the tickets)
It depends on how many kids are coming to the dance in order to fully solve this problem.

It is a good idea to check to see if your answer is reasonable because a. if your answer is reasonable, you have probably done the problem correctly.
2015:
250 members
$95 annual subscription
2016
250 members + 4%
$95 annual subscription + 6%
Work:
250 x 1.04 = 260
95 x 1.06 = 100.7
260 x 100.7 = 26,182
Thus, the club makes $26,182 from 260 members who pay a subscription of $100.7
