We have the equation:

p = 1.4n + 480, where:

p represents the amount Trevor is paid for the week

n represents the light sabers Trevor sold

Let's answer question 1:

How much will Trevor be paid if he sells 380 light sabers for the week?

We replace n by 380 in the formula to find p, as follows:

p = 1.4 * 380 + 480

P = You can do the calculations

Let's answer question 2

How many light sabers did Trevor sell if he earned $1,670.00?

We replace p by 1,670 to find n, as follows:

1,670 = 1.4n + 480

1.4n = 1,670 - 480

1.4n = 1,190

Dividing by 1.4 at both sides, we have:

1.4n/1.4 = 1,190/1.4

n = You can do the division
