A shirt is originally priced at $24.50. The shirt goes on sale for 30% the original price. How much money, in dollars to the nea
ludmilkaskok [199]

Answer:

The final cost is 1.07($17.15) = $18.35

Step-by-step explanation:

If the discount is 30%, we can find the discounted price by taking 70% of the original price (since 100% - 30% = 70%).  Substitute the equivalent 0.70 to calculate the discount price:  0.70($24.50) = $17.15.  This is the discounted price.

The final cost is $17.15 times 1.07, which includes the discounted price plus the 7% tax.  That final cost is 1.07($17.15) = $18.35.

svetlana [45]

Answer:

C. The mean is 111.9F and the median is 114.5F.

Step-by-step explanation:

The mean is 111.9 given that (105 + 113 + 122 + 121 + 116 + 118 + 107 + 93)/8 = 111.875 which can be rounded to 111.9 F.

Organizing the values we have:

[93, 105, 107, 113, 116, 118, 121, 122]

We find that the median is going to be between 113 and 116. Therefore:

(113 + 116) / 2 = 114,5

Therefore, the correct answer is option C.
