Complete Question

Kiran buys supplies for the school’s greenhouse. He buys bags of fertilizer and packages of soil. He pays $5 for each bag of fertilizer and $2 for each package of soil, and spends a total of $90. The equation 5f + 2p = 90 describes this relationship.

If Kiran solves the equation for p, which equation would result?

A. 2p = 90 − 5f

B. p = 5f − 90 /2

C. p = 45 − 2.5f

D. p = 85 f /2

A. 2p = 90 − 5f

Step-by-step explanation:

The equation 5f + 2p = 90 describes this relationship.

We are to solve for p, this means to make p the subject of the formula , hence:

5f + 2p = 90

Subtract 5f from both sides.

5f - 5f + 2p = 90 - 5f

2p = 90 - 5f

Divide both side by 2

2p/2 = 90 - 5f/2

p = 90 - 5f/ 2

If Kiran solves the equation for p, the equation that would result is

2p = 90 − 5f .

Further simplified to :

p = 90 - 5f/ 2

Option A is correct.

graph b

step-by-step explanation:

one solution- graph a (clear intercepting point.)

no solution- graph b (they're parallel, there will never be a point of interception.)

infinite solutions- graph c (all points intercept.)
