A car salesperson sells a used car for $9,000 and earns 7, of the sale price as commission. How many dollars does the salesperson earn in
commission?

Step-by-step explanation:

commision = 7% of $9000

commision = 7/100 * $9000

commision = $630

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°
