The goal is to raise AT LEAST $180, so this automatically indicates that the amount of keychains sold with the price must be the same or more than $180.
k = number of keychains
each keychain is $2.25
2.25k ≥ 180
divide both sides by 2.25 to get the k alone
k ≥ 80
The answer is 2.25k ≥ 180, k ≥ 80
(Hope this isn't confusing)
To find the inverse of a function, replace every x in the equation with a y, and replace every y in the equation with an x:

Add 9 to both sides:

Square root both sides to get y by itself:

This equation can be simplified by taking the square root of 9 out of the root:


The inverse of this function is
y = 3 + √x.

A calculator helped me
Answer:
$407.50
Step-by-step explanation:
take 9.75 × 17=165.75
take 9.75 × 25=243.75
add 165.75 and 243.75=407.50
turn into dollars $407.50
The square root would be 3.4 if rounded to the tenths place
