Find three consecutive odd integers with a sum of 75
marusya05 [52]

Answer:

23, 25, 27

Step-by-step explanation:

first integer will be X, second will be (X+2), and the third will be (X+4). They will all be summed up and set equal to 75.

(x) + (x + 2) + (x + 4) = 75

combine like terms:

3x + 6 = 75

subtract 6:

3x = 69

divide by 3 to find value of X:

\frac{3x}{3}  =  \frac{69}{3}

x = 23

plug in X in o red der to finger the rest of the integers.

(X+2)= (23+2)=25

(X+4)= (23+4)=27

Dave makes 20% commission on all of his sales for the week. Last week Dave sold $1000. How much did Dave make?
serious [3.7K]

Answer:

Dave will make $200 for the sales of $1000.

Step-by-step explanation:

Given are:

Rate of commission of Dave = 20%

Total sales = $1000

The amount that Dave will make will be obtained by calculating the 20% of total sales.

For that we will multiply the sales with 0.20

Commission = 20\%\ of\ Sales\\= 20\%\ of\ 1000\\=0.20 * 1000\\= 200

Hence,

Dave will make $200 for the sales of $1000.
