Original shirt cost: $55. current shirt cost $40 find the percent decrease round to the nearest whole percent

Step-by-step explanation:

Original cost  = $55

Current price = $40

Decrease in price = 40-55 = -$15

Percentage decrease =  [(New price - old price)/ old price] *100

Percentage decrease = (40-55)/55] *100

                                  = -0.272727 *100

                                 = -27.27%

To a whole percentage = 27%

Therefore, the cost of the t-shirt decreased by 27%

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.
