Answer:

The average is 12

Step-by-step explanation:

When finding the average of a group of numbers, all you have to do is add all the numbers together and divide by the amount of numbers that you added by. 8 + 12 + 13 + 15 = 48. 48 ÷ 4 = 12

Katelyn does not have enough money to buy items she likes.

Step-by-step explanation:

Amount Katelyn had = $205

Price of one sweater = $48

Price of 2 sweaters = 2*48 = $96

Price of one pair of pants = $34

Price of four pairs of pants = 34*4 = $136

Total price = Price of sweaters + price of pairs of pants

Total price = $96+136$

$Total\ price= \$232$

Sales tax = 6.5%

Sales tax = $\frac{6.5}{100}*232$

$Sales\ tax=\frac{1508}{100}\\Sales\ tax=15.08\ Dollars$

Total amount = Total amount of items + sales tax

Total amount = 232 + 15.08

Total amount = 247.08 Dollars

Therefore,

Katelyn does not have enough money to buy items she likes.
