Let x denote the number of muffins Marian sells in a day to at least make a profit.
So $1.00 × x will be the amount of revenue Marian earns from selling bread (don't mix revenue with profit. Profit = Revenue - Cost)
In order for Marian to make a profit, revenue must be greater than cost in a day.
$1x > 0.8x + (square root)[5x + 7000]
x > 0.8x + (square root)[5x + 7000]
{ ">" this sign is saying "more than" }
0.2x > (square root)[5x + 7000]
{square both sides}
0.04x > 5x + 7000
-4.96x > 7000
4.96x < 7000
x < 7000 ÷ 4.96
Hope this helps you solve! :) So sorry for my wrong judgement earlier..
Honestly I think you are correct, not trying to take your point. :)
You are the treasurer for a local charity. At the beginning of the month
the balance was $820.64. The charity received donations of $500.00,
$55.00 and $25.00. You have an electric bill of $40.64, bill for postage
of $12.75, and rent for $445.00.
The values will be 10 and -6
