6*3= 18 km
30/10 = 3 km per hour then 2:00 to 2:10
Given:
tickets for adults - 25
tickets for kids - 15
initial cost - 450
increase in tickets for kids to - 18
cost after increase - 480
let x be number of adults and y be number of kids
25x + 15y = 450
25x + 18y = 480
subtraction:
25x + 15y = 450
<u>-25x - 18y = -480</u>
0 - 3y = - 30
y = -30/-3
y = 10
There are 10 kids.
25x + 15y = 450
25x + 15(10) = 450
25x + 150 = 450
25x = 450 - 150
25x = 300
x = 300/25
x = 12
There are 12 adults.
All in all there are 12 adults and 10 kids.
to check:
25x + 15y = 450
25(12) + 15(10) = 450
300 + 150 = 450
450 = 450
25x + 18y = 480
25(12) + 18(10) = 480
300 + 180 = 480
480 = 480
Answer:

Answer:
$64
Step-by-step explanation:
Remaining money = 1 - fraction spent
Remaining money = 1 - (1/4 + 1/8)
Remaining Money = 1 - 3/8
Remaining Money = 5/8
$40 = 5/8 of Starting amount
Starting amount = $40 * 8/5
Starting amount = $64
We need to see the first function
