To find how much you are earning for interest, do 7 x 6.5      

Since 6.5 is 6.5% of 100.    7 x 6.5 = 45.5     

This means that from 6.5% of $700 is $45.50.

Please include the instructions when you post a question.  Thanks.

Use the formula A = P*e^(rt).

Here, A = $700*e^(0.065*t), where t is the # of years (which you have not yet included in your post).

As an example:  After 2 years you'll have   A = $700*e^(0.065*2), or A=$797.18, in your account.

You want to rent a car for the day.Prestige car rentals charges $47 plus $0.07 per mile to rent a midsize vehicle . Gateway Auto
jolli1 [7]

Answer:

240 miles

Step-by-step explanation:

Given that:

Charges offered by Prestige car rentals for renting a midsize vehicle:

Fixed charges = $47

Per mile charges for renting a midsize vehicle = $0.07

Charges offered by Gateway Auto for renting a midsize vehicle:

Fixed charges = $35

Per mile charges for renting a midsize vehicle = $0.12

To find:

Number of miles for which both the companies charge the same price?

Solution:

Let the number of miles for which both the companies will charge the same price = x miles

Charges for one mile by Prestige car rentals = $0.07

Charges for x miles by Prestige car rentals = $0.07x

Total charges by Prestige Car rentals = $47 + $0.07x

Charges for one mile by Gateway Auto = $0.12

Charges for x miles by Gateway Auto = $0.12x

Total charges by Gateway Auto = $35 + $0.12x

As per question statement, the charges are same:

\$47 + \$0.07x = \$35 + \$0.12x\\\Rightarrow 12=0.05x\\\Rightarrow x=\dfrac{1200}{5}\\\Rightarrow \bold{x=240\ miles}

Holland added three decimals that made a sum of 2. One of the decimals was 0.34. What are two other decimals Holland could have
bogdanovich [222]
Using x to represent our missing values and the fact that there are two missing values gives us x + x = 2x. Because it's the sum of these numbers and 0.34, we get the equation 2x + 0.34; now we set it equal to 2, 2x + 0.34 = 2. 

To solve, 1st subtract 0.34 on both sides to get 2x = 1.66. Now divide by 2 on both sides to get x = 0.83. 

So your decimals are 0.34, 0.83, and 0.83
