astra-53 [7]

Answer: Our required equation will be s=2000+0.2d

Step-by-step explanation:

Since we have given that

Base salary of Karen = $2000

Rate of commission on all of her sales = 20%

We need to write a equation:

Let the total salary of her be 's'

Let the number of dollars of merchandise sold be 'd'

According to question, it becomes

s=2000+\frac{20}{100}\times d\\\\s=2000+0.2d

Hence, our required equation will be s=2000+0.2d

Alborosie

Answer:

Kindly check explanation

Step-by-step explanation:

Given the following :

Total Amount made = $250

Amount charged = $70 per car

Tips earned = $50

Equation 1 to represent the above

(Amount charged per car × number of cars) + tips earned = total amount made

Let number of cars = c

Hence,

$70c + $50 = $250

Part B:

Total Amount made = $250

Amount charged = $75 per car

Tips earned = $35

Cost of supplies per car washed = $5

Equation 2:

(Amount charged per car × number of cars) + tips earned - (cost of supplies × number of cars) = total amount made

$75c + $35 - $5c = $250

$70c + $35 = $250

C) Equation 1 does not include the cost incurred in getting the car washed while equation 2 takes into account the cost incurred in washing a car which is then subtracted from the amount charged per car. Also the tips earned in equation 1 is $50 while equation has a tips fee of $35

(2x-2/2) = (15-6x)
2x-1 = 15 -6x
2x+6x = 15 +1
8x = 16
8x/8 = 16 /8
x = 2
