Tabitha bought one dozen socks for $9.00. how much would 18 socks have to sell for in order to be a better deal? explain using unit rates

Step-by-step explanation:

Find the unit rate of each pair of socks for the dozen. 12/9=1.3333

so then multiply 18 by 1.33 to get 23.92. So you could sell the 18 pair pack of socks for anything less than $23.92

Hope this helps ^-^

area of part 1:

a1=base*height/2=(8+2)*(8-2-2-1)/2=10*3/2=15 ft^2

area of part 2:

a2=length*width=(8+2)*1=10 ft2

area of part 3:

a3=length*width=8*2=16 ft2

total shaded area : a1+a2+a3=41 ft2

total area of the reactangle : a=16*8=128 ft2

total area of the nonshaded region : 128-41=87 ft2

2y+y=5

add 2y and y
