Question

Dots sells a total of 247 tshirts (2$) and shorts ($4) in april sales were $536 how many tshirts and shorts did dots sell6

Answer 1

Answer: 226 T-shirts and 21 shorts

Explanation:

Let the number of T-shirts be x and the number of shorts be y

Hence,

2(x)+4(y)=536

Divide both parts of the equation by 2:

x+2y=268

x+y+y=268

(x+y)+y=268

(x+y)+y-(x+y)=268-(x+y)

y=268-(x+y) (1)

x+y=247 (2)

Substitute equation (2) into equation (1):

y=268-247

y=21

Hence,

x+21=247

x+21-21=247-21

x=226
