Write an equation that relates the number of peppers, n, and the<br><br> cost, C.
SCORPION-xisa [38]

Complete Question:

The local Farm Market sells peppers at five for $2.25. Write an equation that relates the number of peppers, n, and the  cost, C.

Answer:

C = 0.45n

Step-by-step explanation:

Given

5\ peppers = \$2.25

Required

Determine the relationship between C and n

5\ peppers = \$2.25

Divide both sides by 5, to get the cost of 1 pepper

\frac{5\ peppers}{5} = \frac{\$2.25}{5}

1\ pepper = \frac{\$2.25}{5}

1\ pepper = \$0.45

Multiply both sides by n to get the cost of n pepper

n*1\ pepper = \$0.45*n

n\ pepper = \$0.45n

So, we have:

C = 0.45n

If y varies inversely asx, and y = 33 when x = 7 what is the constant and what is value of y when x=11?
allsm [11]

Answer:

We have that y = 21 when x = 11.

Step-by-step explanation:

We solve this question by proportions, using a rule of three.

Since they vary inversely, we apply the inverse rule of three, that is, with lateral multiplication instead of diagonal.

33 - 7

y - 11

So

11y = 33 -7

y - 11

Dividing both sides by 11

Y = 3 * 7 = 21

We have that y = 21 when x = 11.
