A local bakery has a daily operating cost of $1800 plus a cost of $10 per cake
they make. If a cake sells for $15, which equation could be used to determine the
minimum number of cakes, c, they must sell each day to earn a profit? *

A. 15c < 1,800 + 10c

B. 15c > 1,800 + 10c

C. 10c < 1,800 + 15c

D. 10c > 1,800 + 15c

B. 15c > 1,800 + 10c

Step-by-step explanation:

Profit=Total revenue - total cost

Profit is achieved:

when total revenue is greater than total cost

TR>TC

Or

When total cost is less than total revenue

TC<TR

From the question

Total cost=1800+10c

Total revenue=15c

Profit=TR>TC or TC<TR

15c>1800+10c

Or

1800+10c<15c

Option B. 15c > 1,800 + 10c satisfies the condition that Profit=TR>TC

B. 15c > 1,800 + 10c

Step-by-step explanation:

The local bakery has an operating cost of $1800 plus a cost of $ 10 per cake produced. The operating cost is the expenses required to run the business. This is the amount required to keep the bakery company in existence. To make a profit, the sales each day must surpass the operating cost.

Since they sell only cakes , the sales of cakes for that day should surpass the operating cost for that day in order for them to make gain

operating cost = 1800 + 10c

where

c = number of cakes sold each day

The price for each cake = $15 . The sales for each day will be 15 × c(the number of cake sold) which should be greater than the operating cost  1,800 + 10c for them to make profit.

15c > 1,800 + 10c

the answer is (4,3)

since the rule for r0, 90º is (-y,x) and it was already applied to form the image, all you have to do is reverse the answer using this formula.
