Answer:
3 pairs for the price of two.
Step-by-step explanation:
$10 per pair
then:
3 pairs costs $20
20/3 = $6.6667 each pair
- Buy one and get 25% of the second
25% = 25/100 = 0.25
then:
first pair $10
second pair: 10 - (10*0.25) = 10 - 2.5 = $7.5
first + second pair = 10 + 7.5 = 17.5
2 pairs costs $17.5
17.5/2 = $8.75 each pair
then:
the best deal:
3 pairs for the price of two.

I think this is the equation
Answer:
Kindly check attached picture ; 37.5%
Step-by-step explanation:
Let:
S = number of science fiction movie viewers
H = number of horror movie viewers
A = number of adventure movie viewers
From the information given :
n(SnHnA) = 5
n(SnH) only = 15 - 5 = 10
n(SnA) only = 25 - 5 = 20
n(AnH) only = 5 - 5 = 0
n(S) only = 40 - (10+5+20) = 5
n(H) only = 40 - (10+5+0) = 25
n(A) only = 50 - (5 + 20 + 0) = 25
2.) % of science fiction movie to horror movie fans
Total Science fiction movie fans = n(S) = 40
Science fiction and Horror movie fans = n(SnH) = 15
[n(SnH) / n(S)] * 100%
(15 / 40) * 100%
0.375 * 100%
= 37.5%
Answer:
<em>Cost paid daily when using the motorcycle: $37,</em>
<em>Cost paid for each kilometer driven in the motorcycle: $ 0.23 </em>
Step-by-step explanation:
<em>~ Let us first formulate the equations, provided x ⇒ cost paid daily when using the motorcycle, and y ⇒ cost paid for each kilometer driven in the motorcycle ~</em>
8x + 650y = 445.5, and 12x + 920y = 655.6
<em>Now let us solve this equation through elimination, by multiplying the first equation by 3, and the second by -2:</em>
3 ( 8x + 650y = 445.5 ) ⇒ 24x + 1950y = 1336.5 ⇒ 110y = 25.3
+ -2 ( 12x + 920y = 655.6 ) + -24x - 1840y = - 1311.2 <em>y = 0.23</em>
<em>Now we can substitute this value of y into the first equation as to solve for x: </em>8x + 650 ( 0.23 ) = 445.5, 8x = 296, <em>x = 37</em>
<em>* Cost paid daily when using the motorcycle: $37,</em>
<em>Cost paid for each kilometer driven in the motorcycle: $ 0.23 *</em>
