Kenny can buy 15 t shirts and 3 sweatshirts.
Step-by-step explanation:
Given,
Number of members = 18
Cost of each t shirt = $9
Cost of each sweatshirt = $15
Money = $180
Let,
x be the number of t shirts
y be the number of sweatshirts
According to given statement;
x+y=18 Eqn 1
9x+15y=180 Eqn 2
Multiplying Eqn 1 by 9
Subtracting Eqn 3 from Eqn 2
Dividing both sides by 6
Putting y=3 in Eqn 1
Kenny can buy 15 t shirts and 3 sweatshirts.
