· The senior class is planning an end of the year party to celebrate graduation. Their total budget for food and drinks is $600. Each plate of food costs $5, and each drink
costs $1. Each person at the party gets one plate of food and one drink, with none
leftover. How many people went to the party?

Solve problem using systems of equations.

100

Step-by-step explanation:

Because everyone had one plate and one drink, we can combine those individual prices.

5 + 1 = 6

Now we divide 600, the total cost, by 6, the cost for one person.

600 ÷ 6 = 100

So now we know that 100 people went to the party, as there was nothing left over.

constant of proportionality = 3 and the equation is c = 3p.

step-by-step explanation:

c = kp   where c = amount of caffeine in mg., p = oz of pepsi and k is the constant of proportionality.

substituting the values given:

24 = 8k

k = 3.

the same value of k will be obtained if we substitute the other given values.
