A caterer prepares three times as many pizzas as she usually prepares for a large party.The caterer usually prepares 5 pizzas. The caterer also estimates that each party guest will eat 1/3 of a pizza. Write an expression that represents this situation. How many party guests will the pizzas serve?

Answers

Answer: There are 45 party guests who will be served pizzas.

Step-by-step explanation:

Since we have given that

Number of pizzas usually prepare by the caterer = 5

Part of pizza will eat by each party guest is given by

$(1)/(3)$

As we have given that a caterer prepares 3 times as many pizzas as she usually prepares for a large party,

So, it becomes

$\text{Number of pizzas prepare by carterer this time}=5* 3=15\n$

Let the number of party guests be x

According to question, it becomes,

Number of party guests will get the pizza serve is given by

$(1)/(3)* x=15\n\nx=15* 3\n\nx=45$

Hence, there are 45 party guests who will be served pizzas.

3 x 5 pizzas = 15 pizzas
1/3 of pizzas x people = 15 pizzas
people = 15 pizzas / (1/3) = 45

You want to buy the bicycle that is $116. You already have $43.50 saved and plan to save an additional $7.25 every week.Part A: Write and solve an equation to find the number of weeks you need to save before you can purchase the bicycle.

Part B: How much sooner could you purchase the bicycle is you had a coupon for $20 off and saved $8.75 every week? Explain your reasoning.

PLEASE HELP! I'M IN 7th GRADE...AND I NEED TO GET MY MATH HOME WORK DONE, AND MY PARENTS AR'NT HOME TO HELP MEE..THANK YOU!

Answers

A. since you already have $43.50 already saved you subtract that from the amount the bike cost so you can see how much more needs to be left to save and that gives you $72.50. Then you divide the amount your saving up every week from that. So $72.50 divided by $7.25 is 10 and thats how many weeks it will take to save.

B. Since you still have that $43.50 saved and you have a coupon for $20 dollars off . Add those together to see how much you have saved up which equals $63.50. The bike is $116 so you subtract the amount you have for the bike from $116 which is $63.50 and that equals $52.50 and thats how much more money you need. Then divide how much money needed by the amount your saving up a week, which is $8.75. So $52.50 divided by $8.75 is 6 and thats how many weeks it will now take to get the bike.
