Answer:
The linear equation is
.
Explanation:
Given : A loaf of bread of similar quality in the store costs $1.60. This is the rate for a loaf of bread (the slope). As there is no other cost, your beginning point (y-intercept) is zero.
To find : Write the linear equation y = mx + b for the total cost.
Solution :
The linear equation for the total cost

Where, m is the slope m=1.6
b is the y-intercept b=0
Substitute the value,


Therefore, the linear equation is
.
