Answer:
x = (40/4)-7.50
x= (10)-7.50
x = 2.50
Step-by-step explanation:
each boy had 2.50 left after the movie because miguel went with 3 other boys, which makes four of them all together. If they had forty dollars all together and all had the same amount of money, you can determine that amount by dividing forty(total money) by 4(number of boys). Which gets you to the answer of ten dollars each. Then you subtract the ticket cost(7.50) from 10 dollars, which gets you to 2.50 left over.
If you have to write the equation then it would be "5k + 6.7"
So the answers are :
A: 5 seconds
and
B: 10 seconds
