The price of a sweatshirt at a local shop is twice the price of a pair of shorts. the price of a t-shirt at the shop is $4 less than the price of a pair of shorts. brad purchased 3 sweatshirts, 2 pairs of shorts, and 5 t-shirts for a toal.

let w represent the price of one sweatshirt, t represent the price of one t-shirt, and h represent the price of one pair of shorts. write a system of three equations that represents the price of the clothing.

The answer to your question is below

Step-by-step explanation:

Equation 1

                            $sweatshirt = 2 pair of shorts

                                     w = 2h

Equation 2

$t-shirt = $pair of shorts  - $4

                                     t = h - 4

Equation 3

Total cost = 3 sweatshirts + 2 pairs of shorts + 5 t-shirts

Total cost = 3w + 2h + 5t = 136    

a system of three equations that represents the price of the clothing are

w = 2h

t = h - 4

3w + 5t + 2h = 136

Step-by-step explanation:

Let w represent the price of one sweatshirt.

Let t represent the price of one T-shirt.

Let h represent the price of one pair of shorts.

The price of a sweatshirt at a local shop is twice the price of a pair of shorts. This means that

w = 2h

The price of a T-shirt at the shop is $4 less than the price of a pair of shorts. This means that

t = h - 4

Brad purchased 3 sweatshirts, 2 pairs of shorts, and 5 T-shirts for a total of $136. This means that

3w + 5t + 2h = 136

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.
