40%= $41.97 + 40%=$41.97 = 83.94
that is 80%now to find the 20% i dividied the 40% which is $20.98 so then I added the 80% and 20% which is $104.92
so the original price is $104.92
40%=83.94
+
40%=83.94
+
20%=20.98
=104.92
Answer:
The number sold at $12.50 is 25
The number sold at $9.50 is 62
Step-by-step explanation:
Hi, to answer this question we have to write a system of equations:
x 12.50 + y 9.50=901.50
x+y= 87
Where
x= number of pottery pieces sold
y= number of pottery pieces sold at a decreased price
Multiplying the second equation by 9.50, and subtracting the second equation to the first equation:
12.50 x + 9.50y = 901.50
-
9.50 x+ 9.50 y= 826.5
__________________
3 x = 75
Solving for x
x =75/3
x = 25
Replacing x=25 on any equation:
x+y= 87
25+y =87
y=87-25
y= 62
Answer:
The answer is 14
