Answer:
width = 11, len = 19
Step-by-step explanation:
length = 2w - 3
l = length
w = width
2(length) + 2(width) = perimeter
2(2w - 3) + 2(w) = 60
6w -6 =60
w = 11
len = 2(11) - 3
Answer:
Store C has the lowest price of $7.00
Step-by-step explanation:
Store A's sale gets you 15% off the shoes. 15% of 35 is $25.50
Store B's sale gets you $5.00 off the shoes. $35.00 - $5.00 = $30.00
Store C's sale gets you 1/5 off the shoes. 1/5 of $35.00 is $7.00
That means that the only true statement is the Store C's shoes are $7.00
