Question

I need helpp ASAP….please

Answer 1

Explanation:

Your initial equations are: r is rate i is initial fee

59.4 = r(240) + i

74.4 = r(490) + i

solve the systems of equations. I eliminate i by multiplying both sides of top equation by -

74.4 = r(490) + i
-59.4 = -r(240) - i

15=250r

r=.06

plug r back in to get i

59.4=(.06)(240)+i

i=45

so

y=.06x+45

Answer 2

the formula is y=0.06x + 45

A. The rate of change is 0.06 dollars per kilometer

B. The initial cost is $45 dollars

C. The charge after 837 km is 95.22 including the initial cost
