1 pizza costs $0.50 to make. They sell it for $12. Find the percent markup.
Answer:
ok let me try this again
To explain a markup, let's use an example: Let's say you purchase a box of paper that costs one dollar. You aim for a profit of 50%. By multiplying the cost by 50%, you get $0.50. This is your markup price. Add that to the price that you paid to purchase the box of paper, and now the total is $1.50. This is the selling price of the box of paper. Therefore, your markup percentage is 50%.

Answer:
not similar
Step-by-step explanation:
For the triangles to be similar, at least two angles must match. Here, there is an 81° angle in both triangles. This means the sum of the remaining two angles must be ...
180° -81° = 99°
If the missing angle in either triangle matched the other given angle in the opposite triangle, the sum of those would be 60° + 40° = 100°, not 99°. This triangle pair does not have two matching angles, so the triangles are not similar.
ABC angles: 60°, 81°, 39°
FED angles: 59°, 81°, 40°

a baker makes 130 loaves so that there are 6 times as many white loaves as granary loaves. half as many brown loaves as white loaves how many of each type does he make
Answer:
Answer: 78 whites, 13 granary, 39 brown.
Step-by-step explanation:
For each 6 whites, there is 1 granary, and 3 brown. That adds up 10 loaves, so just multiply all those numbers by 13.
The Number of white, brown and granary bread loaves are ; 78, 39 and 13 respectively.
Total loaves of bread = 130
Let :
Number of granary loaves = xTherefore,
Number of white loaves = 6x Number of brown loaves = (1/2 × 6x) = 3xThis means that :
Number of white + brown + granary loaves = 130(6x + 3x + x) = 130
10x = 130
x = 130÷ 10
x = 13 loaves
Therefore,
Number of granary loaves = 13 Number of brown loaves = 3(13) = 39Number of white loaves = 6(13) = 78Learn more : https://brainly.com/question/18796573

If the area of a square is increased by 69%, then the side of the square is increased by what percent?
Answer:
Percent Increase in measure of the side of a square = 30%
Step-by-step explanation:
Let the measure of the side of a square = s
Area of the square = (Side)²
= s²
If the area of the square is increased by 69%
Area of the new square = s² + 69% of s²
= s² + 0.69s²
= 1.69s²
Therefore, measure of the side of the new square = √(Area of the square)
= √(1.69s²)
= 1.3s
Measure of side of the old square = s
Therefore, increase in measure of the square = 1.3s - s
= 0.3s
Percent increase in the measure of the side of the square
= [tex]\frac{\text{Increase in measure}}{\text{Measure of the side of the original square}}\times 100[/tex]
= [tex]\frac{0.3s}{s}\times 100[/tex]
= 30%
