Raymond just got done jumping at super bounce trampoline center. the total cost of his session was \$43.25$43.25dollar sign, 43, point, 25. he had to pay a \$7$7dollar sign, 7 entrance fee and \$1.25$1.25dollar sign, 1, point, 25 for every minute he was on the trampoline. write an equation to determine the number of minutes (t)(t)left parenthesis, t, right parenthesis that raymond was on the trampoline.

So if the dude spent $43.25 in total, looking at the question his costs were:
$7 for entrerance
$1.25 each minute on trampoline

 if its easier for you forget the dollar sign so you just focus on the numbers

u need to find how many minutes the dude was on the trampoline for 

first what you do is:
43.25- 7= 36.25
so there is no orfer just common sense, cant subtract the amt it costs per minute cz u dont know how long he was jumping for. 

so u just subtract the entrenace fee

then :
36.25/1.25
total without fees divided by amount per minute
to see how many times 1.25 goes into 36.25
gives you= 29

so the dude jumped for 29 minutes in total
buy it says to write an equation:

so you do:
1.25(t)+7= 43.25
u don't include 29 because its only asking to Write an equation to determine the number of minutes (t)

so the final answer is 
1.25(t)+7= 43.25

21 is the answer the answer is 21
