I got these problems wrong in class. but, think i have the right answer now. Can you check?
1. Jim's mother made pizzas for his birthday. SHe sliced the pizzas into 50 slices. She served Jeff and his 7 guests the same number of slices and she ate the rest. How many pieces of pizza did Jim's mother eat?
Steps: take 50/8 = 6.25; then multiply 8 guests * 6 slices = 48; then subtract 5048 = 2. So, Jeff's mom at 2 piece of pizza.
2. Mrs. Smith made coffee for 7 members of her bridge club. Her coffee maker makes 30 cups. If she and her club members drink equal amounts, how many cups of coffee will still be in the coffee maker when her guests leave?
Steps: take 30/7 = 4.28; then mulitply 7 members * 4 = 28; then subtract 3028 = 2. SO there's 2 cups left.

Your first one is right.
But your second is wrong. How many people are drinking coffee?

1 correct.
2 I am not certain it is right. How many are there, 7 or 8. I am not certain she is a member of the bridge club in the count of 7. My best guess, is you are correct, she is one of the seven. But honestly,your teacher could have thought differently. If they are playing bridge, 4 to a table, 8 total makes much more sense, and your answer then is not what the teacher intended.

So for #2, I should have divided by 8 members? 30/8 = 3.75; but 8*4 = 32 which is more than 30cups. I'm not sure how to solve this now.

What is 8 * 3?

oh.. so you multiplied 8 * 3 instead of 4. But, I thought I needed to round 3.75 up to 4. But, if using 8 *3, then 3024 = 6. There are 6 cups left over. So, when shouldn't i round up? THe 1st problem with the pizza, I also rounded up.

Nevermind.. 1st problem was 6.25 and stayed at 6 because that would be the same amount for everyone. For #2, 3.75 was the average. But, need to stay at whole cup which would 3 for everyone to have equal amount, right?

1. This one is ok.
2. The coffe cups should be divided by 8. If you were to make a drink for the club you would certainly have a drink. The answer is
30/8= 3.75; then you would multiply 8 * 3= 24; then you would subtract 3024 you you would have 6 cups left.
