Answer:
5087.75
Step-by-step explanation:
8.25/100=0.0825*4700=387.75 +4700=5087.75+775=5862.75
The answer is probably ss or SSA depending on your answer choices, if one of these isnt an answer choice let me know
We can use the points (1, 10) and (-8, 3) to solve.
Slope formula: y2-y1/x2-x1
= 3-10/-8-1
= -7/-9
= 7/9
Best of Luck!
