Answer:
percent means <u>per hundred </u>
Between the 100 squares, 60 of them are shaded
so you do 60/100
it's kind of like correcting tests, you have 100 questions, you got 80 of them right so its going to be 80/100
when you calculate percentage, you do the fraction x 100
so it's 60/100 = 0.6 x100 = 60%

Step-by-step explanation:
multiply the hourly rate by number of hours worked
12.75 x 35.25 = 449.44 per week
449.44 x 2 = 898.88 for two weeks
One way to look at this is to make 2 equations and treat it as a set of equations. We will make the cost of a donut equal to x, and the cost of a coffee equal to y.
Harold's order:
4x + 2y = 4.08
Melinda's order:
2x + 3y = 3.92
To combine these equations, we need to cancel out either x or y:
4x + 2y = 4.08
<span>2x + 3y = 3.92
</span>
4x + 2y = 4.08
<span>4x + 6y = 7.84
</span>
4x + 2y = 4.08
<span>-4x - 6y = -7.84
</span>
We can now combine these equations:
4x + 2y = 4.08
<span>-4x - 6y = -7.84
</span>
-4y = -3.76
y = 0.94
Therefore the cost of a large coffee is $0.94. We can plug this into either original equation to find the cost of a donut.
<span>4x + 2y = 4.08
</span>4x + 2(0.94) = 4.08
4x + 1.88 = 4.08
4x = 2.20
x = 0.55
The cost of a donut is $0.55, and the cost of a large coffee is $0.94.
