Let's begin by listing out the information given to us:
We start out by observing that Triangles MKR & ACD are similar or proportional

We will solve for the missing side by using the similar triangle theorem. This is shown below:~
multiply 12,800 x 15 = 192,000 then divide 192,000 by 100 = 1,920 so the answer is $ 1,920. Hope this helps!
64° i think because. its an iscoceles triangle so the bottom two angles are the same so you do 58+58=116 and because all angles in a triangle add to 180° you do 180-116=64°
Answer:
i just stole your points thank you
We solve as follows:
*First: We determine the percentage of store purchases:

*Second: The ratio is obtained as follows:

So, the ratio is 11 to 9 purchases.
