To steam rice, Paul uses m cups of water for every p cups of rice. In terms of m and p, how many cups of
water are needed to steam p + 2 cups of rice?

Step-by-step explanation:

Given

m cups of water = p cups of rice

Required

Cups of water required for p + 2 cups of rice

The question shows a direct proportion between cups of rice and cups of water.

So, the first step is to get the proportionality constant (k)

This is calculated using the following expression;

Where k represents cups of water and p represents cups of rice

Make k the subject of formula

Let x represents cups of water when cups of rice becomes p + 2;

k becomes:

Equate both expressions of k; to give

Multiply both sides by p + 2

Hence, the expression that represents the cups of water needed is

answer: 1, 3 and 5 are correct
