Answer :
Final answer:
The purchase of 5 kg rice and 2 kg wheat for Rs. 99 can be represented by the linear equation 5R + 2W = 99, where R is the price per kg of rice and W is the price per kg of wheat. This equation depicts the total costs of the grains.
Explanation:
When you purchase 5 kg of rice and 2 kg of wheat, the total cost is Rs. 99. This can be represented in a linear equation, where each commodity's weight is assigned a specific price (R for rice and W for wheat). We can conclude that 5R+2W=99 is the linear equation representing your shopping trip.
The first step is to determine what we know. We know the quantities of rice and wheat you bought and the total you spent. Since we don't know the individual prices of rice and wheat, they'll represent the variables in our linear equation. Let's denote rice as R and wheat as W.
You bought 5kg of rice and 2 kg of wheat for a total cost of Rs. 99. This gives us the equation 5R + 2W = 99. To find the individual prices of rice and wheat, you would need more information or another independent equation involving R and W.
