Question

Dots sells T-shirts ($3) and shorts ($7). In April, total sales were $520. People bought 2 times as many T-shirts as shorts. How many T-shirts and shorts did Dots sell?

Answer 1

t shirts=80
shorts=40

Answer 2

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
`=3*2x`

so, total price of shorts
`=7x`

now, we are given

total sales were $520

so,

total price of T-shirts+total price of shorts = total sales

we will get equation

`3*2x+7x=520`

now, we can solve for x

`13x=520`

`x=40`

so,

number of shorts is 40

number of T-shirts is 2*40=80............Answer
