Answer 1

Answer:

Equation: $y = 14x$.

It would take Martina 37 hours to earn $518

Step-by-step explanation:

✍️An equation that shows a proportional relationship between the time she spends babysitting (x) and amount of money she earns for babysitting (y) can be represented as $y = kx$, where k = constant of proportionality.

Let's find k using any of the pairs given in the table of values. Let's use (1, 14).

Substitute x = 1, and y = 14 into $y = kx$, and find k.

$14 = k(1)$

$14 = k$

Substitute k = 14 into $y = kx$.

✅The equation would be:

$y = 14x$.

✍️Using the equation, we can find how many hours Martina needs to work in order to earn $518 she wants to use to buy a new phone.

Simply, substitute y = 518 in $y = 14x$.

$518 = 14x$

Divide both sides by 14

$\frac{518}{14} = x$

$37 = x$

✅Thus, it will take Martina 37 hours to earn $518
