Answer:
C = 5x + 8y + 15z + 1.5r + 15
Where C = cost for the family of 6
Step-by-step explanation:
Let:
x = number of children under 10
y = number of children 11-16
z = number of all others (16 and above)
r = number of rides
Cost:
Under 10 = $5
11-16 = $8
Above 16 = $15
Ticket Ride = $1.50
We have an additional $15 for parking
So from there, we can find the cost by getting the total:
Cost for each TOTAL
x x $5 $5x
y x $8 $8y
z x $15 $15z
r x $1.50 $1.50r
Constant : $15 for parking
So the expression would then be:
C = 5x + 8y + 15z + 1.5r + 15
Given:
6 family members
x = 3
y = 1
z = 2
r = 5
We fill in the formula
C = 5x + 8y + 15z + 1.5r + 15
C = 5(3) + 8(1) + 15(2) + 1.5(5) + 15
C = 15 + 8 + 30 + 7.5 + 15
C = 75.50
Answer: b)
Step-by-step explanation:
Given,
speed of train A travelling east = 55 mph
speed of train B travelling west = 70 mph
time train A travelled while train B was at rest = 45 min or
so, Distance travelled by train A while train B was at rest =
=
Now, after 'T' hour both the train will travel;
train A = 55T
train B = 70T
hence, the distance (D) between two train in miles will be;
⇒ D = 41.25 + 55T + 70T
⇒ D = 125T + 41.25
-1 716/1000 can be simplified by getting and touching the fraction part. Just don't mind yet the whole number part.
The numerator 716 and the denominator 1000 are divisible by 4. So divide the numerator and denominator by 4
716 / 4 = 179
1000 / 4 = 250
So the new fraction is -1 179/250
Converting it to improper fraction, we get.
-429/250
