Which of the following is a rate? 24 apples for $3 12 apples for $1.50 8 apples for $1 16 apples for $2

Answer:The only rate is 8 apples for $1.Step-by-step explanation:When we are going to purchase then the shopkeeper says the rate of 1 apple is x$ or he says that in 1$ you can purchase x number of apples. So, in case of a rate statement, either the price or the number of apples will be unity. So, 24 apples for $3 is not a rate, and 12 apples for $1.5 is not a rate again 16 apples for $2 is also not a rate.  Therefore, the only rate is 8 apples for $1. (Answer)
