Answer 1

Answer:

(a) $y=8x+5$

(b) 7 hours.

Step-by-step explanation:

(a) Let x be the number of hours and y is the total cost.

We have been given that Beatrice and her friends charge $8 per hour of babysitting, so the charges for x hours of babysitting will be 8x.

As they also charge a mandatory $5 per day fee for each child for snacks, so the total charges for babysit each day will be charges for x hours of babysitting plus mandatory charge.

We can represent this information in an equation as:

$y=8x+5$

Therefore, the equation $y=8x+5$ represents the total cost of using Beatrice’s babysitting service each day.

(b) To find the number of hours Beatrice babysit the daughter, we will substitute y = 61 in our equation and solve for x.

$61=8x+5$

Let us subtract 5 from both sides of our equation.

$61-5=8x+5-5$

$56=8x$

Let us divide both sides of our equation by 8.

$\frac{56}{8}=\frac{8x}{8}$

$7=x$

Therefore, Beatrice babysit 7 hours the daughter.
