Answer:
38 normal tees and 24 striped
Explanation:
There are two equations you will want to set up:
One will be the total amount of shirts sold (let x be normal tee shirts and y be striped)
x + y = 62
And then one for the cost
15x + 22y = 1098
Now multiply the first equation by -15 so we can use the elimination method so
-15x - 15y = -930
15x + 22y = 1098
Now we can add those together and the x terms will cancell leaving
7y = 168
Divide by 7
y = 24
Now sub back into the amount of shirts equation
x + 24 = 62
Subtract 24:
x = 38
