Question

A discrete relationship is shown below between the number of workers on the job and the number of bricks

Answer 1

Answer:

$b = 90w$

Step-by-step explanation:

Required

Determine the relationship

Represent the workers with w and bricks with b

First, we need to determine the constant of proportionality using:

$b = kw$

Solve for k

$k = \frac{b}{w}$

When w = 1; b = 90:

$k = \frac{90}{1}$

$k = 90$

When w = 2; k =180

$k = \frac{180}{2}$

$k = 90$

Notice that $k = 90$ in both cases;

Substitute 90 for k in $b = kw$

$b = 90w$

Hence; the relationship is $b = 90w$
