Lois is paid 245 per week plus a 12% commission on all sales. his gross pay was $1320 last week. what was her amount of total sales?

We know Lois's gross pay is

... gross pay = $245 + 12%×sales

And we are given gross pay. So, we can substitute the given information and solve for sales.

... $1320 = $245 + 0.12×sales

... ($1320 -245) = 0.12×sales

... sales = $1075/0.12 = $8958.33

Lois's amount of total sales last week was $8958.33.
