Answer:

(a) The total number of tokens purchased = 9

(b) The cost of 1 token = $1.458

Explanation:

Here the cost of 1 bus token = $ 1.75

The total amount spent on the tokens = $15.75

(a) Let us assume the number of token purchased = m

So, here, the cost of m tokens = m x ( Cost of 1 token)

= m x ($1.75) = 1.75 m

Also, cost of m token = $15.75

⇒$15.75 = 1.75 m

or, m = 15.75/1.75 = 9

or, m = 9

Hence, the total number of tokens purchased = 9

(b) The number of token purchased = 10

So, the amount paid for 10 tokens = 10 x ( cost of 1 token)

= 10 x ( $1.75) = $17.5

Now, 2 token are free with 10 purchased token.

So, total token now = 10 + 2 = 12

The amount paid for 12 token = $17.5

So, here the cost of each token =
(17.5)/(12)   =1.458

Hence, the cost of 1 token = $1.458
