You buy 6 apples for $2.70 write and equation that can be used to express the relationship between the total price t and the number of apples a you buy. 1. t= 2.70a

2. t=0.45a

3. t=6a

t= 2.22a

The correct answer is: 2. t=0.45a

Step-by-step explanation:

Let t be the price of apples

and a be the number of apples

The price and quantity are directly proportional

Removing the proportionality symbol introduces a proportionality constant in the equation

So far we know that cost of 6 apples is $2.70

Putting in the equation

Putting the values of k will give us:

Hence,

The correct answer is: 2. t=0.45a
