PLEASE ANSWER QUICK! THANK YOU! Beatrice decides she wants to babysit a few children at the same time to earn the money faster. She tells parents that if they allow her to babysit their children at her house, she will eliminate her automatic $5 tip and will give them an additional $5 discount.
(d) Write an equation showing the total cost for each client. Identify all variables.
(e) Four parents bring their children to Beatrice’s house at the same time for babysitting. Beatrice wants to find out how many hours she must babysit the 4 children to earn exactly the $100 she needs in order to buy the present for her mother. Write and solve an equation to find the number of hours. Justify each step in the solution.
(a) One parent decides not to drop off her child. The remaining 3 parents drop their children off at 9 a. m. Two of the parents say they will be back at 1 p. m. The third parent says she will pick up her child at 2 p. m. At noon, Beatrice realizes she needs help feeding the 3 children at the same time. She tells her little sister that she will pay her if she helps feed the children. How much can Beatrice pay her little sister and still make sure she has enough money to buy her mother a $100 present? Show your work and justify your answer. (I'm confused on how to do this, please help! Here are some tips☟)
Write an equation in the form y = mx + b where m is the amount charged per hour, b is the discount, and y is the total cost.
Distribute the 4 on the left side of the equation. Add 20 to both sides. Divide both sides by 40.
First, calculate how many hours Beatrice will babysit each child. To find out how much each parent will pay Beatrice, multiply the number of hours for each child by 10 and subtract 5. Add the amounts for the 3 children to get the total amount Beatrice will be paid. Subtract $100 from this amount to find out how much Beatrice can pay her sister.
