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..
Number of the tickets for the qualifying matches:

4 10/8 breaks down to 5 2/8 = 5 1/4
3 1/2 + 1 3/4
3 1/2 = 3 2/4
3 2/4 + 1 3/4 = 4 5/4
the correct answer is 5 1/4
so yes, your answer IS correct!
Speed of snail 1 = 3.795 cm/minute
Speed of snail 2 = 4.795 cm/minute
<em><u>Solution:</u></em>
Given that,
Total distance = 189 cm
They crawl towards each other at rates that differ by 1 cm a minute
Let the speed of snail 1 be "x"
Let the speed of snail 2 be "x + 1"
Total time = 22 minutes
Since the snails are moving towards each other,
Speed = x + x + 1 = 2x + 1
<em><u>How fast is each snail crawling?</u></em>

Thus,
Speed of snail 1 = 3.795 cm/minute
Speed of snail 2 = 3.795 + 1 = 4.795 cm/minute
