Ok so f(x) really just means y so ur equation is
y=4x+25
Answer: The total cost is
assuming the cost for 1 adult is
and the cost for 1 child is 
Step-by-step explanation:
Assuming the cost for 1 adult is
and the cost for 1 child is
:
and 
Then the expression that gives the total cost
is solved as:

Answer:
The price for one cone before tax is $2.26.
Step-by-step explanation:
The tax for each cone is $.17
Ronnie buys six cones. The total tax for the cones is 6 X $.17 = $1.02
Next, we subtract the total taxes from the total price $14.58 - $1.02 = $13.56
So Ronnie owed $13.56 for the six cones BEFORE taxes. We takes this amount and divide it by six to get the cost for one cone.
$13.56 / 6 = $2.26 per cone.
Check our work
Purchase one cone for $2.26 plus $.17 cents tax = $2.43 total cost per cone.
6 cones at $2.43 each would be 6 X $2.43 = $14.58.
This matches the total bill from the story problem.
Answer:
The number of problems solved = 2000
Step-by-step explanation:
Let us assume the monthly quota of problems be x
number of problem solved in first week = 25 % of x =
number of problems solved in 2nd week = 110% of (problems solved in 1st week)
= 
=
number of problem solved 3rd week= 60% of ( problems solved in 1st and 2nd week)
= 
=
=
number of problem solved in 4th week = 
now we have
number of problems solved in ll 4 weeks = x






Hence the number of problems solved = 2000
