P = 2(L + W)
P = 58
L = 3W + 1
58 = 2(3W + 1 + W)
58 = 2(4W + 1)
58 = 8W + 2
58 - 2 = 8W
56 = 8W
56/8 = W
7 = W <=== width is 7 inches
L = 3W + 1
L = 3(7) + 1
L = 21 + 1
L = 22 <=== length is 22 inches

Answer:
Mary removed the dollar sign from (X.)
We know this because $4.00x$5.00=$20.00 so that’s correct and we know that $12.50x $4.00=$50.00. So, our only error here is that there is no dollar sign in our (X) numbers. So that is Mary’s mistake. We can correct it by simply adding a dollar sign to 20 to make $20.00 and adding another dollar sign to 50 to make $50.00
