ursula earns $9 per hour. to write an expression that tells how much money ursula earns for h hours, josh wrote 9\h. sarah wrote 9h. whose expression is correct and why

Answers

Answer 1

Answer: The important information's already given in the question can be used to find the correct answer.
In 1 hour Ursula earns = 9 dollars
So
In h hours Ursula earns = (9/1) * h dollars
= 9 * h hours
= 9h hours
So we have found from the above discussion that Sarah wrote the correct answer and it was 9h.I hope you are satisfi3ed with the answer and theexplanation that I have provided. You can use this procedure for solvingsimilar problems.

Answer 2

Answer:

Sarah is correct because if Ursula is earning $9 per hour then every hour you can add 9. Lets say h=2 then you would multiply 9*2 to get how much she spent. Josh is incorrect because dividing would subtract the amount of money every our.

Hope this Helps

Answer:

f-1(x)=x-4

f-1(4)=0

Step-by-step explanation:

to get an inverse function, replace x with y, and y with x.

y=x+4 ---> x=y+4

solve for y: x=y+4 --> y=x-4 --> f-1(x)=x-4

f-1(4)=(4)-4=0

rohit marks his goods at 40% above the cost price but allows a discount of 5% on cash payment to his customers. What actual profit does he make if he recieves rs 1064 after allowing the discount?

Answers

Goods are marked 40% above cost price but 5% discount is given.
Therefore, total profit = (40 - 5)%
= 35%
Let the cost price be 'x.'
So, (35% of x) + x = 1064
( $(35)/(100)$ *x) + x = 1064
$(7x)/(20)$ + x = 1064
   $(7x)/(20) + (20x)/(20)$ = 1064
   $(27x)/(20)$ = 1064
Therefore:
27x = 1064*20
27x = 21,280
x = $(21280)/(27)$
x = Rupees 788.14
Cost price is Rs. 788.14
Profit = 35% of 788.14
   $(35)/(100)*788.14$
Total profit = Rupees 275.849
