Alec's total payment for his loan was $19,440. what was his monthly payment if he paid it off after making 60 monthly payments?
a. $298
b. $312
c. $324
d. $336

C. $324.

Step-by-step explanation:

We have been given that Alec's total payment for his loan was $19,440.

To find the amount of Alec's monthly payment we will divide the total amount by total number of monthly payments.

Therefore, Alec's monthly payment was $324 and option C is he correct choice.

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.

y=-2.5x+12.5

step-by-step explanation:

5y=2x+10

y=0.4x+2

slope=-2.5

5=-2.5*3+b

b=12.5
