Answer:
I'm pretty sure it's 13.
Step-by-step explanation:
RT = 8 , RS = 3 AND ST = 5.4
RV = 4 , RU = 1.5 AND UV = 2.7
∴ RT/RV = 8/4 = 2
AND RS/RU = 3/1.5 = 2
AND ST/UV = 5.4/2.7 = 2
∴Δ RTS IS SIMILAR TO ΔRVU
SO, the best statement is:
Each pair of sides corresponds with a common ratio of 2.

This is all I know sorry if this was unhelpful!
You take the discount first. Alex is completely right. Laura is if and only if that 110% is really just 10%. So I'll use Alex's method because it is for certain correct.
28.5*35/100 = 9.975 (which is the amount of the discount)
28.5 - 9.975 = 18.525 (which is the amount paid with the discount factored in.)
Now you take 10% of this amount and add it on which gives 18.525 * 10/100=1.825 which is the amount of the tax.
Add this on to the selling price 18.525 + 1.825 = 20.3775 and now is the time to do your rounding.
The cash register will ring up 20.38 which is just under $21.00
