The mean decreases, think about it, if every single value in a data set was decreased by the same number, the average would also go down by the same number

The median would also go down, because the value in the middle of the data set would now be smaller than before

The mode would also decrease, because the value that showed up the most in the data set has now also been decreased

The range, however, stays the same. If the lowest value in a data set was 3 and the highest was 10 and you subtracted 2 from each value in the data set, you would have the lowest at 1 and the highest at 8. But, 10-3 still equals 8-1, so the range is unchanged

Ulleksa [173]

Answer:

A. Equation is $c=25+15.75x$

B. Cost is $88

Step-by-step explanation:

Suppose you rent for x hours and each hour costs $15.75

<u><em>How much would you need to pay?</em></u>

$15.75x$

Moreover, there is a $25 dollar (fixed) deposit for renting, so that gets added to your payment. All in all, you have to pay $25+15.75x$

This is the equation of renting a snowboard for x hours.

Equation is $c=25+15.75x$

Where x is the number of hours you rent the snowboard, and
c is the total cost

If you are renting from 8.30 to 12.30, you are basically renting for 4 hours.

To know how much it will cost, you simply plug in 4 into x (in the equation):

$c=25+15.75x\\c=25+15.75(4)\\c=88$

Cost is $88
