Which equation represents the table shown?
hours money ($)
15 127.50
25 212.50
35 297.50
a. y = 8.5x b. y = 8.5x + 12.50 c. y = 15x d. y = 15x + 12.509

the answer is y=8.5x

Step-by-step explanation:

because x would equal the hours and y would equal the money.

so you divide y by x, so in this case it would be 127.50/15 and that equals 8.5

so the multiplier or constant of proportionality, if thats what you guys call it, is 8.5.

answer: the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.

step-by-step explanation:

the given rate of interest i= 85%

in calculating the monthly payment for a loan with an interest rate compounded monthly, the value of the interest rate per period we use in the formula must be in decimal form.

to convert it in decimal, we divide it by 100, we get

hence, the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.
