Question

2. Mr Roy buys potatoes at * 12/kg and onions
at 14/kg. If he buys x kg of potatoes and
3 kg less onions than the potatoes, find the
algebraic expression for his expenditure.​

Answer 1

Answer:

26x-42

Step-by-step explanation:

let x kg represent potato

therefore onion is 3kg less than potato= x-3

So, his expenditure can be expressed as

price of potato times x kg + price of onion times x-3 kg

= 12x + 14 (x-3)

= 12x + 14x - 42

= 26x - 42
