Let's assume
number of shorts is x
we are given
People bought 2 times as many T-shirts as shorts
so, number of T-shirts is 2*x=2x
Dots sells T-shirts ($3) and shorts ($7)
so, total price of T-shirts 
so, total price of shorts 
now, we are given
total sales were $520
so,
total price of T-shirts+total price of shorts = total sales
we will get equation
now, we can solve for x
so,
number of shorts is 40
number of T-shirts is 2*40=80............Answer
Answer:
A = 4 pi R^2 V = 4/3 pi R^3
A / V = 3 / R
Also, R = (3 * V / 4 * pi)^1/3 = (3 * 904.32 / (4 * pi))^1/3 = 6 in
So A = 3 / 6 * V = 1/2 * 904.32 = 452.16 in^2
Start out by adding 50 to both sides.
2x - 50 + 50 = 150 + 50
which simplifies to
2x = 200
then divide both sides by 2
2x ÷ 2 = 200 ÷ 2
which simplifies to
x = 100
And that is your answer! Hope this helps :)
1. Ryan had 4 people coming over but each second person brought 5 different people, let X represent the number of people brought along, what is X?
2. Lexy has 456$ she gave it to four friends. Let M represent how much she gave each friend if she was left with 50$ What does X equal?
