Question

Karen had 50 dollars. She bought k soda-pops which cost c dollars each. How much money does she have left?

Answer 1

If you want an equation, it should be 50-kc=m. She starts with 50, then subtracts however many sodas (k) that cost c dollars. The end product is m for money. I hope this helps!

Answer 2

Let T represent the total money left, therefore, equation for money left becomes:

`T=50-kc`

Explanation:

Karen had 50 dollars.

She bought k soda-pops which cost c dollars each.

So, total cost of 'k' soda pops can be given by = kc

Now, money left with Karen will be =
`50-kc`

Let T represent the total money left, therefore, equation for money left becomes:

`T=50-kc`
