Answer:
-1.5x + 70
Step-by-step explanation:
Total money he takes while going to the fair = $90
Money he spends to enter the fair = $5
Money he spends on food =$15
Total he spent now is given by
Now, he spend on rides at the fair i.e. 1.50 per ride .
Let the number of rides be x
So, cost incurred on rides = 1.5x
So, the spending money can be expressed as
Now, remaining money left to him after spending on x rides too is
Let f(x) denotes the function used to determine the money he has left over after rides .
So it becomes
f(x) = 70 - 1.50x
f (x) = -1.50x +70
Answer:
G-7×17=119
Step-by-step explanation:
A prime number is a number which has only two factors, 1 and itself.
A composite number on the other hand is any number that has more than two factors.
In the options
In F-5×15=75, 15 can still be decomposed into 5X3
In H-9×19=171, 9 can still be decomposed into 3X3
In J-11×21=231, 21 can still be written as 7X3.
So option G is the only equation which could show Brodricks work.
B. 4 minus the quotient of a number and 3
The quotient means the number you get after dividing, so
x/3 would give you the quotient, which is then subtracted from 4
Answer:
Kevin should do 21 shock replacements and 6 brake replacements every week to maximize his weekly income.
Step-by-step explanation:
Since either job takes 2 hours to complete, the total number of jobs that Kevin can complete working 54 hours a week is:

Since replacing shocks gives him a greater income, he should aim to do as little break replacements as possible and as many shock replacements as possible in order to maximize income.
If he has to complete at least 6 break replacements out of the 27 jobs possible, the number of shock replacements he should do is:

Kevin should do 21 shock replacements and 6 brake replacements every week to maximize his weekly income.
