Question

Reuben sells beaded necklaces. Each large necklace sells for $5.10 and each small necklace sells for $4.60. How much will he earn from selling 1 large necklace and 7 small necklaces?

Answer 1

Reuben will earn $37.30 from selling 1 large and 7 small necklaces.

Explanation:

Let's create a formula for calculating how much Reuben will earn from selling necklaces:

First, let's call what he will earn `e`.

Then the number of large necklaces we can call `l` and for large necklaces he sells he will make `l xx $5.10`.

Also, the number of small necklaces we can call `s` and for small necklaces he sells he will make `s xx $45.60`.

We can put this altogether to get our formula:

`e = (l xx $5.10) + (s xx $4.60)`

In the problem we are told to calculate for Reuben selling 1 large necklace which we can substitute for `l` and 7 small necklaces which we can substitute for `s` and then we will be able to calculate `e`:

`e = (1 xx $5.10) + (7 xx $4.60)`

`e = $5.10 + $32.20`

`e = $37.30`
