The best way to do this one is by multiplication. If you have two dozens of eggs, you multiply two by a dozen to find out how many eggs you have: 2*12=24. Similarly, if you have two fifths of 20 apples, you multiply 2/5 by 20 to find out how many apples you have: (2/5)*20 = 8.

25,000(4+3x) =125,000
Amanda [17]
To solve this equation, first we have to use the distributive property to eliminate the parentheses on the left side of the equation.

If done correctly, your simplified equation should be 

100,000 + 75,000x = 125,000

Next, we would subtract 100,000 from both sides, resulting in the equation

75,000x = 25,000

Finally, we would divide both sides of the equation by 75,000, resulting in your final answer of 

x= 25,000/75,000

However, many mathematics teachers ask for fractional answers to be simplified.  To simplify fractions, we first find the GCF of both numbers, and then divide both the numerator and the denominator by the GCF.

The GCF of 25,000 and 75,000 is 25,000.

So, in simplest form, your final answer is 

x=1/3

If the car dealer pays 85% of the base price and 75% of the installed options price from the manufacturer,
stira [4]

Answer:

$18,007,50

Step-by-step explanation:

First, you have to calculate the 85% of the base price that the dealer pays for the car:

base price: $18,750

$18,750*85%= $15,937.5

Second, you have to calculate the 75% of the installed options price that the dealer pays:

installed options price= $2,380

$2380*75%= $1,785

Third, you have to add the 85% of the base price plus the 75% of the installed options that the dealer has to pay and you also have to add the destination charge of $285:

$15,937.5+$1,785+$285= $18,007.5

According to this, the dealer has to pay $18,007.5 for the car with a base price of $18,750 and installed options price $2380  including a destination charge of $285.
