Answer:
Store A: $440.00
Store B: $412.50
Step-by-step explanation:
The graph for store A and the equation for store B both represent linear equations. Linear equations form a straight line because there is a constant rate of change. In this case, the rate of change for both store is the cost per T-Shirt. Looking at the graph for store A, we see that for every 10 T-shirts sold, there is a profit of $40, so after 10 t-shirts, the profit is $40 and after 20 t-shirts the profit is $80. If we divide 40/10, we get $4 per t-shirt. For store B, the equation y = 3.75x is given, where 'x' represensents the amount of t-shirts and 'y' represents the total profit. In this equation, the 3.75 would be the cost per t-shirt. If each store sells 110 t-shirts, we would multiply the cost by the number sold:
110 x 4 = $440.00
110 x 3.75 = $412.50
