Step 1: Calculate part (non-100%).
The first step is to identify the amounts needed to be added together to calculate the portion of the budget that has already been spent, which represents the part (non-100%).
75 + 65 = 140
Making 140 the part (non-100%).
Step 2: Divide the part (non-100%) by the whole (100%).
In order to find the percentage, we have to divide the part of the total available amount by the total amount available.
140 ÷ 680 = 0.2058823529
We can round this off to the third-place value. Check your answer choices to see if numbers were rounded to a different place value.
0.2058823529 → 0.206
Step 3: Multiply by 100.
Now that we have our decimal, we have to turn it into a percent.
0.206 × 100 = 20.6%
This tells us how much of the budget has already been spent. Finally, we have to find the percentage of what she has left.
Step 4: Subtract budget spent from total budget.
The event coordinator spent 20.6% of her budget. In order to find the percentage that is left we will subtract the percentage she spent from 100%.
100% – 20.6% = 79.4%
The event coordinator has 79.4% of her budget left.

Step 1: Interpret the problem.
We need to find the surface area of the box.
Step 2: Break your shape down into its net.
When we break down a rectangular prism into its net, we have six rectangles, a top and a bottom, a front, and a back, and two sides.

Step 3: Determine how to find the area of each part of the net.
Let’s first find the area of the top and the bottom rectangles of the prism.
length × width = area
The length of the top rectangle is 11 in and the width is 8 in.
11 in × 8 in = 88 in²
The area of the top and bottom rectangles are 88 in² each.
Now we find the area of the front and back rectangles.
The length of the front rectangle is 11 in and the width is 5 in.
11 in × 5 in = 55 in²
The area of the front and back rectangles are 55 in² each.
Lastly we find the area of the two side rectangles.
The length of a side rectangle is 8 in and the width is 5 in.
8 in × 5 in = 40 in²
The area of each of the side rectangles is 40 in².
Step 4: Add up the areas of each part of the net.
2 × top area + 2 × front area + 2 × side area = surface area
2 × 88 in² + 2 × 55 in² + 2 × 40 in²
(2 × 88 in²) + (2 × 55 in²) + (2 × 40 in²) = 366 in²
So, Jessica needs 366 in² of gift wrap paper

Step 1: Interpret the problem.
We need to find the total volume of the paint can, and then divide it by 2.
Step 2: Substitute the numbers into the equation.
Volume = π × r² × h
3.14 × (4 in2) × 11 in
Step 3: Solve using the order of operations.
3.14 × (4 in)2 × 11 in
3.14 × 16 in² × 11 in = 552.64 in³
Step 4: Divide the volume by 2 to find the amount of paint.
552.64 in³ ÷ 2 = 276.32 in³
The volume of paint inside the can when it is one-half full is 276.32 in³.
