Dots sells a total of 267 T-shirts ($2) and shorts ($3). In April, total sales were $633.

How many T-shirts and shorts did Dots sell?

Lets

s = # of shorts sell

and

t = # of shirts sell

s + t = 267 so s = 267 - t

3s + 2t = 633

substitute s = 267 - t into 3s + 2t = 633

3s + 2t = 633

3 (267 - t) + 2t = 633

801 - 3t + 2t = 633

-t = - 168

t = 168

s = 267 - t

s = 267 - 168

s = 99

answer

shirts = 168

shorts = 99
