Answer:

16 tvs

Explanation:

Maura's earnings for the week equal her weekly salary (460) plus she earns 6.5% commission x number of flat screens sold x $414.

So: Total Earnings = 460+ 0.065*414*t where t is the number of tvs she has sold.

If total earnings = 890.56, just substitute that above and solve for t.

890.56= 460+ 0.065*414*t

430.56=0.065*414*t

430.56=26.91*t

430.56/26.91 = t

16 = t

She sold 16 tvs to earn 890.56.
