Answer:
Money she have in 25 days = $2850
Money she have in 50 days = $5700
Step-by-step explanation:
Kristy earns each day = $134
Spends on breakfast & lunch = $8 + $12 = $20
Reaming about each day = $134 - $20
= $114
Money she have in 25 days = 25 x $114
= $2850
Money she have in 50 days = 50 x $114
= $5700
Answer:
let cost of each pound of trail mix be x any y respectively
For 2 pounds of trail mix and 5 pounds of jelly beans, the total cost is $10
2x +5y = 10.....(1)
For 8 pounds of trail mix and 3 pounds of jelly beans, the total cost is $23
8x +3y = 23.....(2)
2x +5y= 10 ....... × 4
8x +20y = 40.....(3)
8x +3y = 23 ( from (2))
(3) - (2)
17y = 17
y= 1
8x +3y = 23
8x +3 = 23
8x= 20
x= 2.5
Cost for each pound of trail mix= $2.5
Cost for each pound of jelly beans= $1
The two friends will be 150 miles apart, when the sum of the distances covered by the them is 150 miles.
distance = speed x time.
Let the time covered when they are 150 miles apart be x, then:
40x + 35x = 150
75x = 150
x = 150/75 = 2.
Therefore, the two friends will be 150 miles apart in 2 hours.
