If the relationship between total cost and number of units made is linear, and if cost increases by $1.4 for each additional unit made, and if the total cost of 24 units is $55, find the equation of the relationship between total cost (y) and number of units made (x).

Ответ:
y = 1.4x + 21.4
Step-by-step explanation:
Given :
Total cost and number of units made have a linear relationship
Mathematically,
Total cost, y = b * number of units made, x + c
If cost increases by $1.4 for each additional unit, the slope, b = 1.4
If total cost of 24 units = $55
Total cost = 1.4 * number of units made + c
55 = 1.4*24 + c
55 = 33.6 + c
c = 55 - 33.6
c = 21.4
c = intercept
The linear relationship between total cost and number of units made is :
y = 1.4x + 21.4
