Question

Basir buys 4 small drinks for $6. write an equation to represent the cost, c, for d small drinks.

Answer 1

c x d = total cost
c = $6, d = 4
$6 x 4 = $24

Answer 2

c = $ 1.5 d

Explanation:

Cost of 4 small drinks = $ 6

Cost of one mall drink = $ 6 / 4 = $ 1.5

Let the number of drinks is d and the cost is given by c.

So, the cost of d drinks = $ 1.5 x d

So, c = $ 1.5 d
