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#
