Answer:
<u>The equation is:</u>
<u>We have two points:</u>
A)
<u>Find the slope using these two points:</u>
- m = (99 - 68)/(620 - 310) = 31/310 = 0.1
<u>Use one of the points to find the y-intercept b:</u>
- 68 = 0.1*310 + b
- 68 = 31 + b
- b = 68 - 31
- b = 37
<u>The equation is:</u>
B)
<u>Find the value of y when x = 980:</u>
- y = 0.1*980 + 37
- y = 98 + 37
- y = 135
The total cost is $135
