A car salesman has 8 used cars for sale. They have a mean price of $4500. What is the total price of all 8 cars?
muminat

Answer:

$36000

Step-by-step explanation:

We have a mean price of $4500 this means that in the 8 cars we have cars with higer and lower prices than $4500 but that if we have to give the same price to 8 cars that would be $4500. Then to know the total price of the all 8 cars we just have to multiply:

\$4500\cdot 8=$36000

Can someone please Compare and contrast a line graph to a pie graph and the first one to submit an answer gets brainiest
lara31 [8.8K]

Line graphs can be used to compare changes over the same period of time for more than one group. Pie charts are best to use when you are trying to compare parts of a whole. They do not show changes over time.
