Tom bought six CDs that were each the same price including sales tax he paid a total of $67.80 each CD has a tax of $.50 what was the price of each CD before tax

First, find how much the total amount of taxes were by multiplying.

0.50 * 6 = $3 of taxes.

Second, subtract the total tax amount to the final amount to find the amount of all six CD's before tax.

67.80 - 3 = $64.80 total amount before taxes were applied.

Third, divide to find how much each CD cost.

64.80 / 6 = $10.80 per CD.

Best of Luck!

.50x6=3 total tax

67.80-3=64.80 price of all w/o tax

64.80/6=10.8 price of one w/o tax

$10.80

hello,

b) 62.47% of the students are between 14 and 18 years old.

step-by-step explanation:

mean = 15 and standard deviation = 2

student between 14 to 18

formula used z-score

for age 14 , z score

using z-table , p(z> -0.5)=0.3085

for age 18 , z score

using z-table , p(z< 1.5)=0.9332

p(-0.5< z< 1.5)=0.9332-0.3085 = 0.6247

thus, 62.47% of the students are between 14 and 18 years old.
