A 9-yard roll of string costs $3.42. What is the unit price?

Karolina [17]

Answer:

$0.38 per yard

Step-by-step explanation:

Step 1:

Given; A 9-yard roll of string that costs $3.42.

Required; To find the unit price

Step 2:

Convert $3.42 to cents

$1 ~dollar=100~cents ~\\therefore,\\$3.42=3.42~x~100=342~cents~$

Step 3:

Find the unit price

$\frac{9 yard}{1 yard} =\frac{342 ~cents}{x~cents}$

$9x=342$

$\frac{9x}{9} =\frac{342}{9}$

$x=38~cents$

Convert to dollars

$x=\frac{38}{100}$

$x=0.38~per~yard$

Hence the unit price is $0.38 per yard.

X = Lilys weight
x + 34 = Arthurs weight
4x - 180 = combined weight

x + x + 34 = 4x = 180
2x + 34 = 4x - 180
