Answer:
c = 420t . . . . c is calories burned; t is hours riding at 15 mph
Step-by-step explanation:
There is not enough information given to write a function rule relating all the variables to calories burned. If we assume that calories are burned at the constant rate of 420 calories per hour, then total calories will be that rate multiplied by hours:
c = 420·t
where c is total calories burned by the 154-lb person, and t is hours riding at 15 mph.
___
In general, rates are related to quantities by ...
quantity = rate · time . . . . . where the rate is (quantity)/(time period)
Here there are 20 members in all.
Each member paid $2.60.
Total amount paid by members = 20 × 2.60 = $52
The club paid $47.50 to hire the hall. ......Answer
Hence the amount received by the hall = 52 - 4.50 = $ 47.50
The Hall charged $47.50 as the fee.
