$15,000+$6,500+$23,000+$20,500+$5,000=$70,000
$70,000+$40,000=$110,000
$110,000-$82,000=-$28,000
economic profit is -$28,000
$82,000-$70,000=$12,000
accounting profit is $12,000
They need to babysit for 10 hours to have same money each day.
Step-by-step explanation:
On Thursday;
Charges = $3 per hour
Initial fee = $40
let x be the number of hours.
T(x) = 3x+40
On Friday;
Charges = $4 per hour
Initial fee = $30
F(x)= 4x+30
The cost will be same when;
T(x) = F(x)
![3x+40=4x+30\\40-30=4x-3x\\10=x\\x=10](https://tex.z-dn.net/?f=3x%2B40%3D4x%2B30%5C%5C40-30%3D4x-3x%5C%5C10%3Dx%5C%5Cx%3D10)

Alright! In order to do number 3, you first have to simply what you have. So:
√4x[12-√(10-6)] → √4x[12 ÷ √4]
Now, to find the square root of a number you simply ask yourself, "What number times itself will give me that number?". So, the number two times itself is equal to 4. So:
√4 = 2. Plug in this value for √4.
2x[12 ÷ 2] → 2x6
Multiply:
2x6 = 12
