Bobby pays a $25 membership free to join ymca gym. this gym allows members to attend any exercise class for only $4. the linear equation can be written as t=4c + 25, where t represents the total cost of classes and the gym membership fee. let c represent the number of classes bobby attended. find the cost, t, when bobby went to 2,4,8, and 10 classes.

Step-by-step explanation:

T = 4c + 25where c = # of classes and T = total cost

2 classes...so sub in 2 for c and solve for T

T = 4(2) + 25

T = 8 + 25

T = 33 < with 2 classes ,its $ 33

4 classesso sub in 4 for c and solve for T

T = 4(4) + 25

T = 16 + 25

T = 41 < with 4 classes, its $ 41

8 classessub in 8 for c

T = 4(8) + 25

T = 32 + 25

T = $ 57 < with 8 classes, its $ 57

10 classes...sub in 10 for c

T = 4(10) + 25

T = 40 + 25

T = 65 < with 10 classes, its $ 65

this is the formula: v = the value of investment at the end of the time period

p = the principal amount (the initial amount invested)

r = the annual interest rate

n = the annual frequency of compounding (how many times a year interest is added)

t = the number of years the money is invested

^ means raise to the power of

answer: it is 8

step-by-step explanation:

you know why its 8
