30% = .3
120 x .3 = 40
120 + 40 = 160

Complete question :
Anastasia uses the equation p = 0.7(rh + b) to estimate the amount of take-home pay, p, for h hours worked at a rate of r dollars per hour and any bonus received, b. What is an equivalent equation solved for h? A. h = (h equals StartFraction p Over 0.7 EndFraction minus b divided by r.– b)÷ r b. h = h equals StartFraction p Over 0.7 EndFraction minus b divided by r.– b ÷ r c. h = h equals left-parenthesis StartFraction p Over 0.7 EndFraction right-parenthesis divided by r minus b.÷ r – b d. h = h equals StartFraction p minus b Over 0.7 EndFraction divided by r. ÷ r
Answer:
[(p/0.7) - b] / r
A. h = (h equals StartFraction p Over 0.7 EndFraction minus b divided by r.– b)÷ r b. h = h equals StartFraction p Over 0.7 EndFraction minus b divided by r.
Step-by-step explanation:
Given the equation :
p = 0.7(rh + b)
Make h the subject
Divide both sides by 0.7
p / 0.7 = 0.7(rh + b) / 0.7
p/ 0.7 = rh + b
Subtract b from both sides :
(p/0.7) - b = rh + b - b
(p/0.7) - b = rh
Divide both sides by r
[(p/0.7) - b] / r = rh/ r
[(p/0.7) - b] / r = h
Answer:
She has 27 students now.
Step-by-step explanation:
Given :
The teacher has 30 students
10% students left.
To find : how much students does she have now?
Solution :
Since we are given that teacher has 30 students .
And 10% of students left
⇒ 10% of 30
⇒
⇒
⇒
Thus, 3 students left .
She had 30 students . three students left.
So, now she have 30 - 3 = 27 students .
Hence she has 27 students now.
