The Carr School Band purchases pizza and drinks for their end-of-year celebration. Each pizza costs $10 and each drink costs $2. A total of 62 items (pizza & drinks) are purchased for a total price of $220. If p = the number of pizzas and d = the number of drinks, which system represents this situation?

4n + 100 = C

7n = C  

by elimination 7n - 4n - 100 = 0

3n = 100

n = 100/3 (33.33)

*need to sell 34 pizzas

n= number of pizzas

c= cost

Step-by-step explanation:

Step-by-step explanation:

p+d=62 and 10p+2d=220

Not sure if you need solution, but

p=62-d, using this p in second equation gives you

10(62-d)+2d=220

620-10d+2d=220

-8d=-400

d=50, and since p=62-d

p=12

So the band purchased 50 drinks and 12 pizzas.

c 1 hour

step-by-step explanation:

m = 2e

m = 2 so 2 = 2e

1 = e

the 8 in 8,420 is in the thousands place so it's value is 8 thousand.

the 8 in 6,870 is in the hundreds place so it's value is 8 hundred.

divide 8000 by 800 to find the answer:

8000 / 800 = 10

the 8 in 8,420 is 10 times greater than the 8 in 6,870
