# Thread: 8th grade math problem involving pizzas and some kind of algebra

1. ## 8th grade math problem involving pizzas and some kind of algebra

I have a problem where there are 3 people making 3 different kinds of pizza. it shows me how many pizzas were made by each person for each of 5 hours. Cheese: 6, 12, 8, 16, 12 Pepperoni: 5, 2, 7, 4, 9 and Veggie: 2, 8, 4, 16, 8. Then it goes directly to: the last hour(hour 10) 210 pizzas were made for each type of pizza. how many were cheese, veggie, pepperoni?
I actually found the answer but have no idea how they got the answer. Can anyone help?
Thanks!

3. The answers I found somewhere online:
Cheese 128
pepperoni 10
veggie 72

or I may have written it wrong and it's
cheese 72
veggie 128
pepperoni 10

4. It's not clear to me how these answers were arrived at with the information you have given.

5. ok, I think I have it figured out, but not sure if there is a simpler way:

Cheese pizza: hour 1=6 hour 2=12 hour 3=8 hour 4=16 hour 5=12
(if this pattern is correct then hour 6=24 hour 7=20 hour 8=40 hour 9=36 and hour 10=72)

Pepperoni: hour 1=5 hour 2=2 hour 3=7 hour 4=4 hour 5=9 (hour 6=6 hour 7=11 hour 8=8 hour 9=13 hour 10=10)

veggie: hour 1=2 hour 2=8 hour 3=4 hour 4=16 hour 5=8 (hour 6=32 hour 7=16 hour 8=64 hour 9=32 hour 10=128)

So now: do I solve for ALL 10 hours? Or just the 10th hour? and isn't there an easier way to solve than have to rack my brain searchign for complex patterN?

6. Please post something more clear or people may not be able to answer you

7. I'd love to post something more clear, but that's the problem and I don't know how to answer the problem.
