Q:
A popular donut shop spends \( \$ 0.10 \) per donut to produce their award-winning donuts. I
addition, they pay \( \$ 1100 \) in utilities and \( \$ 5100 \) in salaries and benefits per month.
a) Defining \( E \) as the total monthly expenses and \( d \) as the number of donuts produced,
write an equation of the expenses to the number of donuts.
Equation:
b) The store manager calculated the total expenses for March as \( \$ 14150 \). Use the equati
to determine how many donuts were produced in March. Round to the nearest whole
donut.
c) The shop sells each donut for \( \$ 0.50 \). What was the shop's revenue in March?
Revenue in March: \( \$ \square \)
d) How much profit did the store make in March?
Profit: \( \$ \)

Q:
A popular donut shops uses the following two equations to calculate their revenue and
their cost.
The cost is calculated using \( E=0.15 n+6800 \) where \( E \) represents the monthly
expenses, and \( n \) is the number of donuts that the shop made that month.
The revenue is calculated using \( R=0.85 n \) where \( R \) is the monthly revenue, and \( n \) is the
number of donuts sold that month.
Calculate the monthly break-even point. Round your answer to the next largest donut.
\( n=\square \) donuts
