I would do 120 - 45. Now that she has 75 left I would do 75 - 15 * 3 Since 45 Is all that she has left.
If I were you choose a variable I would say h for hours. And h is equal to 3.
In result the whole equation would be 120 - 45 - 15 * h but since h is equal to 3 , We can write it as 120 - 45 - 15 * 3. Leaving Audrey with $30 left.
Correct me if I am wrong :)
Answer:
The number of times over the Weekend that:
Ashley watched TV = x = 12 hours
Gabby watched TV = y = 6 hours
Step-by-step explanation:
Let us represent:
The number of times
Ashley watched TV = x
Gabby watched TV = y
Together, Ashley and Gabby watched a total of 14 hours of television over the weekend.
= x + y = 14..... Equation 1
x = 14 - y
Ashley watched 6 times as many hours as Gabby.
x = 6y
Using substitution method
We substitute 14 - y for x
14 - y = 6y
14 = 6y + y
14 = 7y
y = 14/7
y = 2 hours
Solving for x
x = 14 - y
x = 14 - 2
x = 12 hours
Therefore:
The number of times over the Weekend that:
Ashley watched TV = x = 12 hours
Gabby watched TV = y = 6 hours
