best rentals charges a daily fee plus a mileage fee for renting its cars. barney was charged $159 for 3 days and 300 miles, while mary was charged $289 for 5 days and 600 miles. what does best rental charge per day and per mile?
Answers
Answer:
Let charge per day be $x and charge per mile be $y
then:
as per the given condition we have;
3x + 300y =159 .....[1]
5x + 600y = 289 .....[2]
Multiply equation [1] both sides by 5 we get;
Using distributive property:
15x+1500y = 795 .....[3]
Multiply equation [2] by 3 both sides we get;
Using distributive property:
15x+1800y = 867 .....[4]
Subtract equation [3] from [4] to eliminate x and solve for y;
15x+1800y-15x-1500y = 867 -795
Combined like terms;
300y = 72
Divide both sides by 300 we get;
⇒ y =$0.24 per mile.
Now substitute this value y in equation [1] to solve for x;
3x + 300(0.24) =159
3x + 72 =159
Subtract 72 both sides we get;
3x + 72 -72 = 159 -72
Simplify:
3x = 87
Divide both sides by 3 we get;
Therefore, the best rental charges per day is, $ 29 and the charges per mile is, $0.24

The price of the robotics kits after both discounts is $25.5
What is a discount price?
The price at which something is sold, after reducing some amount from the regular price, is called discount price.
Given that, you have a coupon for an additional 25% off the price of any sale item at the store. the store has put a robotics kit on sale for 15% off the original price of $40.
Here, two discounts are given, at 25% and at 15%
Therefore, the selling price (price after the discounts) = 40x(100-25)/100x(100-15)/100
= 40x75/100x85/100
= 51/2
= 25.5
Hence, the price after the discounts is $25.5

40 * 15% =
= 40 * 15/100 =
= 40 * 3/20 =
= 2 * 3/1 =
= 2 * 3 =
= 6 [dollars]
So the kit costed $40 - $6 = $34 after the first general discount. Now the question is if the coupon relates to the original price or to the lowered price. We'll do both:
If it relates to the original price, we need to find how much is 25% of $40. We can do it in mind - it's $10. So with two discounts the price would be $40 - $6 - $10 = $24.
However, if it relates to the lowered price, we need to find how much is 25% from $34:
34 * 25% =
= 34 * 25/100 =
= 34 * 1/4 =
= 8.5 [dollars]
So the final price in such a situation would be $40 - $6 - $8.5 = $25.5.

Where s is the length of the side of the cube.
6s² = 294
s² = 294/6
s² = 49
√s² = √49
s = 7
Length of one side = 7 cm.
I hope this helps.
SURFACE AREA OF CUBE = A = 6*S^2.......WHERE S= SIDE OF THE CUBE
VOLUME OF CUBE = V = S^3
6S^2=294 SQ.CM.
S^2=294/6 = 49 = 7*7
S=7
V = 7^3 = 343 CU.CM.
