Answer:
Levi must sell more than 80000 cars per month for the new job to be better than the current job.
Step-by-step explanation:
New Job;
He receives $800 per month plus a commission of 2% or 0.02 of the total price of the cars.
Now, let the total amount he receives in a month be "y" and let the amount of cars sold be x.
Thus;
y = 800 + 0.02x - - - -(eq1)
Current Job:
He receives $1200 per month plus a commission of 1.5% or 0.015 of his total sales.
Thus;
y = 1200 + 0.015x - - - (eq2)
Substituting 800 + 0.02x for y into eq(2) gives;
800 + 0.02x = 1200 + 0.015x
0.02x - 0.015x = 1200 - 800
0.005x = 400
x = 400/0.005
x = 80000
This means Levi must sell more than 80000 cars per month for the new job to be better than the current job.
8/4 = 2 caps per ball of wool
so 6/2 = 3 balls of wool are needed.
4/8 = x/6
8x/24
x = 24/8 = 3
7x + 18 = 8x
8x-7x = 18
x = 18
3y = 2x
3y = 2(18)
3y = 36
y = 12
Given:
Susie has 34 nickels and dimes. Their total value is $2.35.
To find:
The number of nickels and number of dimes.
Solution:
Let the number of nickels be x and number of dimes be y.
Susie has 34 nickels and dimes.
....(i)
We know that,
1 nickel = $0.05
1 dime = $0.10
Their total value is $2.35.
Multiply both sides by 100.
Divide both sides by 5.
...(ii)
Subtracting (i) from (ii), we get
Putting y=13 in (i), we get
Therefore, number of nickels is 21 and number of dimes is 13.
