Question

A company builds computers. It costs $7,600 to build 10 computers and $12,200 to build 20 computers. Which equation models the cost, C(x), as a linear function of the number of computers built, x?

c(x)=
460x-3000

c(x)=
3000x-460

c(x)=
460x+3000

c(x)=
3000x+$460

Answer 1

plug in y = 7,600 and x = 10
and y = 12,200 and x = 20 to check

Answer 2

Okay !

Answer 3

wait to all of them ?

Answer 4

7600=10*a+b
12200=20*a+b find a and b

Answer 5

y=460x+3000

Answer 6

c(x)= 460x+3000
