Answer:
56.43
Step-by-step explanation:
100% is the cost . With 8% tax added then total cost is 100 + 8 = 108%
multiply the cost by 108% for total cost
52.25 × 108% = 52.25 × = 56.43
square root n+5-square root n-10=1
add sqrt(n-10) on both sides
To remove square root we take square on both sides
Subtract n and add 9 on both sides
Now we divide both sides by 2
Take square on both sides
+-49= n - 10
49 = n-10 and -49 = n - 10
Add 10 on both sides
n= 59 and n = -39
Now we verify both solutions
When n = -39 we will get negative under the square root . that is complex so we ignore n=-39
n = 59 is our solution
