• To solve Questions of type 11 we need to simplify the equation by using mathematical operations !!
• To solve Questions of type ( 13 , 15 and 17 ) we try to make the bar numeral to come other side of decimal
° and by subtracting we get the required fraction !!
<h2 />
Average price=total price/total weight, let p be the average price:
p=(3*4+5*4*(100-20)/100)/8
p=(12+16)/8
p=$3.50/lb
.16
It‘a really easy just do

Answer:
k = 8 + 100 (.25) - 2x
Step-by-step explanation:

Then you have to pay for the 100 key chains at $.25 each so you have to multiply them to get the total cost.
Next you earn 2 dollars for every key chain sold which becomes the 2x. You are then subtracting this from the amount of money you are spending to get k.
