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..
Hello! what I like to do is multiply by 10s and subtract the difference, so one thing you could do is 10x256-(3x256)! your final answer will be 1792, hope this helped! ;)
Answer:
see below
Step-by-step explanation:
Add 4 to find the solution:
z ≤ 7
The value 7 is included in the solution set, so there will be a solid dot at that point. Numbers less than 7 are also included in the solution set, so the number line will be shaded to the left of that solid dot.
