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:
$Y = K*X$
$4.90 = 2*X$
$4.90 = 2X$
$2X = 4.90$
$X = \frac{4.90}{2}$
$\boxed{\boxed{X = \ \:2.45\:each\:box}}\end{array}}\qquad\quad\checkmark$
