4. Thomas is at a store buying school clothes. T-shirts are on sale for $13 each and jeans are on sale for $18 each.
a) Write an equation that represents the total cost for x T-shirts and y pairs of jeans.
I need help with a..
b) Thomas bought six T-shirts and his total bill came to $168. How many pairs of jeans did he buy? Show all your work.
$13 x 6 (T) = $78.00
$18 x 5 (J) = $90.00
$90.00 + $78.00 = $168.00
