Raul has $40
2 answers:
Let, amount of money he can spend on the present before tax=p
The tax on present of cost p =6% of p=0.06p
Amount of money he spent on present after tax= p +0.06p=1.06p
the amount he can spent should be less than 40
So, 1.06p≤40
To get the value of p, let us divide by 1.06 on both sides
p≤37.73 or 37.73≥p

Answer:
Option C.
Step-by-step explanation:
As we can see from the graph, we have plotted the different points.
If the line drawn through the scatter plots, shows the relationship between the length x and mass f(x) then the function will be in the form of
f(x) = mx + b
where m = slope of the line that fits the best
b = y-intercept of the line
Since the plotted line passes through two pints (1, 1) and (10, 94).
Then the slope m =
m =
m =
m = 10.3
Now we place the coordinates (1, 1) in the equation to find the value of y-intercept b.
1 = 10.3 + b
b = 1 - 10.3
b = -9.3 ≈ 9
So the function will be f(x) = 10.3x - 9
Option C is the answer.
