12 fewer means to subtract 12 so you would have h-12
First let establish the eqautionlet y be the total costx is the number of orders
y = 3x + 115
since the minimum order is 25x >= 25
then The school can spend a maximum of $800
800 <= 3x + 115
800 - 115 <= 3x685 <= 3x685/3 <= x228.33 <= x
Answer:
positive 48 ..yan yung pagkakaalam ko
Answer:
$40
Step-by-step explanation:
If you were to purchase 7 picture frames, you would replace x in the equation with 7, this is shown below.
<u>f(x)=9x-23 ---> f(x)=9(7)-23</u>
Now we can solve for f(x). First start with 9(7).
<u>f(x)=9(7)-23 ---> f(x)=63-23</u>
Now finish the last part by subtracting 23 from 63.
<u>f(x)=63-23 ---> f(x)=40</u>
This means that you would have to pay $40 dollars to purchase the 7 picture frames.
