Question

the iron - it - out laundromat dry cleans roxannes suits. there is a proportional relationship between the number of suits roxanne dry cleans, x, and the total cost (in dollars), y. write an equation for the relationship between x and y. simplify any fractions. y =

Explanation:

Step1: Identify proportional constant

From the graph, when $x=1$, $y=10$. The proportional constant $k = \frac{y}{x} = \frac{10}{1} = 10$.

Step2: Write proportional equation

Proportional relationships follow $y=kx$. Substitute $k=10$.
$y = 10x$

Answer:

$y = 10x$
