Question

Yolanda buys 11 bananas for $5.17. How much does one banana cost?

Answer 1

One banana costs `$0.47`.

Explanation:

Lay this question out in an algebraic form. Let bananas be `b`.

`11b = 5.17`

We want the term `b` on its own, so in order to isolate it, we must divide both sides by `11`.

Therefore

`(11b)/11 = 5.17/11`

`b = 0.47`
