Question

A construction contractor used the equation Y=KX to determine it would cost him $4.90 to buy 2 boxes of nails. How much in each box

Answer 1

Data: (adopting)
Y = $4.90
K = 2 boxes
x = ? (how much in each box)

Solving:

`Y = K*X`

`4.90 = 2*X`

`4.90 = 2X`

`2X = 4.90`

`X = (4.90)/(2)`

`\boxed{\boxed{X = \$\:2.45\:each\:box}}\end{array}}\qquad\quad\checkmark`
