Which proportion correctly shows the equivalence of two fractions?
lyudmila [28]

Answer:

B is your answer.

Step-by-step explanation:

Depends on 18/36 = 72/444, because 444 doesn't make sense at all. None of the others are equivalent. If it's 72/144 then this is the answer

Members of the band are selling candy bars to raise money. The director uses this equation to calculate the amount of profit, p,
ivolga24 [154]

Answer:

<h3>C. 800</h3>

Step-by-step explanation:

Given the equation used to calculate the amount of profit, p, made from selling n candy bars expressed as  p = 1.50n – 500

To find the number of candies sold for $700, we are going to substitute p = $700 into the given expression and find n as shown;

700 =  1.50n - 500

Add 500 to both sides

700+500 = 1.50n-500+500

1200 = 1.50n

Divide both sides by 1.50

1200/1.50 = 1.50n/1.50

800 = n

Rearrange

n = 800

Hence 800 candy bars must be sold to make $700 profit
