Simply find the total medium cofees sold
then divide that by the number of medium cofees that weren't caffeinated

so..
$66 \div 44 = x$
then
$100 \div x = percentage$

so x will be 1.5 & 100 ÷ 1.5 = 66.666...
rounded is 67%

$67\%$

Given f(x) = 3x + 4. Find F-1(7)<br><br> Please help I’ll give you brainiest answer 100points!!!!!

Musya8 [376]

Answer:

f⁻¹(7) = 1

Step-by-step explanation:

Step 1: Write out function

f(x) = 3x + 4

Step 2: Find f⁻¹(x) (or known as inverse f(x))

y = 3x + 4

x = 3y + 4

-3y + x = 4

-3y = 4 - x

y = -4/3 + x/3

Step 3: Plug in 7 into inverse f(x)

f⁻¹(7) = 7/3 - 4/3

f⁻¹(7) = 3/3

f⁻¹(7) = 1
