Answer:
A
Step-by-step explanation:
For test A, the unit rate is 30 words per minute divided by 4 minutes, or 7.5 words per minute.
Unit rate = 78 words/15 minutes = 5.2 words per minute for test B.
The unit rate for test C is 99 words/22 minutes, or 4.5 words per minute.
The inverse of this function is f(x) = 
To find the inverse of any function, start by switching the x and f(x) term. Then solve for the new f(x). The result will be the inverse function. The step-by-step process is below for you.
f(x) =
----> Switch the x and f(x)
x =
----> Muliply both sides by 3
3x = -15 + 4f(x) ----> Add 15 to both sides
3x + 15 = 4f(x) ----> Divide both sides by 4.
f(x) = 
Answer:
50 gram
Step-by-step explanation:
The actual percentage recipe = 100%
Percentage Increase in recipe = 60%
Recipe used as a result of increment = 80 gram
Hence,
100% + 60% = 80
160% = 80g
If :
160% = 80
100% = x
Cross multiply
1.6x = 80 * 1
1.6x = 80
x = 80 / 1.6
x = 50
Recipe required 50 gram
