james spent $12 to buy one black T-shirt and $90 for 6 pieces of the grey T-shirt. How much money does he need to buy 2 pieces of black T-shirt and 3 pieces of grey T-shirt?
From the question, one black t-shirt is $12.
6 Grey t-shirts are $90 dollars, and therefore 1 Grey t-shirt is $15
This can also be written as
x=12
y=15
Therefore, 2x+3y=2(12) + 3(15) = 24 +45 = $69
The answer is $69.
Hope that helped!
