Svetllana [295]

To find the percentage of something, simply multiply the percentage (converted into a decimal) and the total. 60% = 0.6. 0.6*1.15 = 0.69.
The markup is $0.69.
To find the retail price, add the markup to the wholesale cost. 0.69+1.15= 1.84.
The retail price is $1.84.
Hope that helped you.

Arturiano [62]

Answer:

$56.25

Step-by-step explanation:

for every hour Dexter worked with his dad he made $12.50 since he worked with him 4.5 hours we have to multiply 12.50*4.5 or if easier add 12.5 four and a half time 12.5+12.5+12.5+12.5= 50 + 6.25 ( which is half of $12.50 because he only worked half an hour) = $56.25

What is the average (with 0 decimal places) across all schools for the total score? Group of answer choices 1287 1215 1221 1229

Answer:

See explanation

Step-by-step explanation:

Required

The average

The data whose average is to be calculated are not given.

However, the formula to calculate the average is:

$\bar x = \frac{\sum x}{n}$

Assume the data is:

$1287\ 1215\ 1221\ 1229$

This means that the number of schools is 4

So:

$\bar x = \frac{1287+ 1215+ 1221+ 1229}{4}$

$\bar x = \frac{4952}{4}$

$\bar x = 1238$

<em>The average of the assumed data is 1238</em>
