A salesman keeps 20% of his sales as a commission. How much does he have to sell to earn $1,000? It is percent proportions by th

BARSIC [14]

If he wants to earn $1000, it means that $1000 must be 20% of his overall sales.

1000 = 20% * x
1000 = 20/100x
1000 = 0,2x / ÷ 0,2 (both sides)
x = 5000

Answer: A salesman must sell products for $5000 to earn $1000.

Sean is driving to visit his friend in another state. In the first hour, he travels 1/5 of the total distance. Second hour he tr

astra-53 [7]

Answer:

The friends live 285 miles apart.

Step-by-step explanation:

Let total distance in miles Sean needs to cover to visit his friend be = $x$

On first hour distance traveled in miles is = $\frac{1}{5}\ of\ the\ total\ distance = \frac{1}{5}.(x)=\frac{1}{5}x$

Distance left to cover after first hour = $x-\frac{1}{5}x$

On second hour distance traveled = 34 miles

Distance to still left to be covered = 194 miles

Total distance to be covered after first hour will be = $34\ miles+194\ miles$ = 228 miles

Thus, the equation can be given as:

⇒ $x-\frac{1}{5}x=228$

Multiplying each term with 5 to remove fractions.

⇒ $5x-5.\frac{1}{5}x=5\times228$

⇒ $5x-x=5\times228$

⇒ $4x=1140$

Dividing both sides by 4.

⇒ $\frac{4x}{4}=\frac{1140}{4}$

∴ $x=285$

Thus, the friends live 285 miles apart.
