Answer:

30-8p

Step-by-step explanation:

Let p represent cost of each drink.

We have been given that the medium pizza costs two times as much as one drink, so the cost of medium pizza would be 2p.

We are also told that the large pizza costs three times as much as one drink,  so the cost of la pizza would be 3p.

We have been given that Mary wants to buy one large pizza, one medium pizza, and three drinks.

Since the cost of one drink is p, so cost of 3 three drinks would be 3p.

The total cost of one large pizza, one medium pizza, and three drinks would be 2p+3p+3p=8p

Mary started with $30, so amount left after all of her purchases would be 30 minus total cost of all purchases.

30-8p

Therefore, Mary will have 30-8p dollars left after making all of her purchases.

S=[E,F,G,H,J] identify the ways to select two members from s allowing the repetition
Fofino [41]

Answer: There are 25 ways to select two members.

Step-by-step explanation:

Since we have given that

S={E,F,G,H,J}

Number of elements = 5

We need to select two members from S allowing the repetition.

We will use "Fundamental theorem of counting":

There are 5 choices for the first member.

There are 5 choices for the second member.

So, Number of ways would be

5\times 5\\\\=25

Hence, there are 25 ways to select two members.

The student council set a goal of raising at least $500 in flower sales. So far it has raised $415.
zzz [600]
Hi There!

Ok, so student council needs 500 dollars from flower sale, and they already have 415, To find how much they need you have to subtract 500-415, your final answer should be 85, so the student council needs $85 dollars more to reach their goal.

Hope This Helps :)
