Question

A single subway token costs $2.25. A machine dispenses eight tokens for $15.00. if you need eight tokens, how much would you save by buying tokens from the machine

Answer 1

you would save 3 dollars

Answer 2

$3.00

Explanation:

Given that a single subway token costs $2.25, and you want to buy eight tokens, you can find the price of eight tokens if you weren't to buy them from the machine, and compare this value to $15.00 (the price if you were to buy them from the machine).

Take the cost of one subway token ($2.25) and multiply this value by 8.

• 
  `2.25(8)`

Input this into a calculator and you would receive:

• 
  `18`

The price of eight subway tokens if you weren't to buy them from the machine is $18.00.

Compare this value to the price if you were to buy them from the machine; $15.00.

Find the difference between these two values (elsewhere-bought - machine-bought) to see how much money you would save by buying the subway tokens from the machine.

• 
  `18.00-15.00=3.00`

You would save $3.00 if you bought the tokens from the machine, rather than from elsewhere.
