I'll give brainliest to whoever answers first and is correct!!
Nina [5.8K]

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.

Expression for part c is missing.

A vendor is selling championship t-shirts for $33.00. After a day, sells were so good, they raised
Zepler [3.9K]

A vendor is selling championship t-shirts for $33.00. After a day, sales were so good, they raised  the selling price by 25%. The amount of percent increase on the t-shirts is $41.25

The selling price is the price at which a good is being sold to a customer.

Given that:

  • The vendor sells championship t-shirts for = $33.00
  • After a day the selling price increased by 25%

The amount of the percent increase on the t-shirts after a day can be estimated as:

\mathbf{= \dfrac{25}{100}\times \$33.00}

= $8.25

Now, after a day, the vendor sold the cloth at the rate of:

= $33.00 + $8.25

= $41.25

Therefore, we can conclude that after a day, the t-shirts is being sold for $41.25 after raising the percentage by 25%.
