The profits from selling t-shirts at store a are shown in the graph. the profit y for selling x t-shirt are store b is represented by the equation y= 3.75x. if the store sells 110 t-shirts, what is their profit.

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

the final amount you will pay is $68.04.

the tip is determined by the pre-tax amount, so we calculate the tip based on the original bill, not after we've added sales tax.

to find the tip:

we can divide 54.00 by 100 to get 1% of 54. then we multiply that by 18.

54 / 100 = .54

.54 x 18 = 9.72

tip = 9.72$

to find the tax:

we can divide 54.00 by 100 to get 1% of 54. then we can multiply that by 8 to get 8%.

54 / 100 = .54

.54 x 8 = 4.32

tax= 4.32

now we can add the tip and tax to the bill to get our total.

54 + 9.72 + 4.32 = 68.04

total: $68.04
