The answer would be x=2 or x=5
N = number of nights
M = number of meals
n = cost per night
m = cost per meal
T = total cost
Nn + Mm = T
They give us two scenarios :
1. N = 3 and M = 1 and T = 250
3n + 1m = 250
2. N = 3 and M = 6 and T = 330
3n + 6m = 330
Thus, we have a system of equations.
In the first equation, solve for m.
m = 250 - 3n
Now, plug this into the second equation and solve for n.
3n + 6m = 330
3n + 6(250 - 3n) = 330
3n + 1500 - 18n = 330
-15n = -1170
n = $78
Now, plug this back into our equation for m and solve.
m = 250 - 3n
m = 250 - 3(78)
m = 250 - 234
m = $16
Thus, it costs $78 per night and $16 per meal.
Answer: $64
Step-by-step explanation:
Given: The part of money he spent =3/4
Let the total money Otto has be 'x'.
Then according to the question, we have
Multiply 4 on both the sides, we get
Divide 3 on both the sides, we get
Hence, the money he had before he bought the game = $64
Answer:
1) 3/20
2) 2/5
3) 45
Step-by-step explanation:
2) P(not Pink) = 8/20 which reduces to 2/5
3) probability of blue is 3/20 which is 15/100; if you multiply the numerator and denominator by 3 you get 45/300
