Answer:
It is 7
Step-by-step explanation:
y = mx+b
y is the total cost.
x is the number of hours.
b : that's 16 dollars.
y = 9x+16
The problem states that the cost was 79 dollars.
Substitute that for y and solve for x.
79 = 9x+16
63 = 9x
x = 7 hours

<h3>What is mathematical model or function?</h3>
A mathematical model or function is the model which is used to explain any system, the effect of the components by study and estimate the functions of systems.
The total number of cookies made by Tania on the Monday is 70 and want to make more than this on Tuesday.
The capacity of the pan is to cook 18 cookies per batch. The function she used to predict the number of cookies is,
y=70+18(x)
Here, x is the number of batches.
The cookies baked by her in 12 batches,
y=70+18(x)
y=70+18(12)
y=286.
Thus, the number of cookies baked by Tanya in 12 batches of 18 cookies per batch including 70 cookies of Monday is 286.
