Step by Step:
Take the amount of movies ( x ) multiplied by the cost of each ( $1.99 ) and add the fee. ( $8 )
Answer:
x = 1/72
Step-by-step explanation:
72(x)=1
We need to isolate x, and since x is being multiplied by 72, we can isolate it by dividing both sides by 72.
72x/72 = 1/72
x= 1/72
X = cups of tea per hour
y = cups of coffee per hour
David makes 30 cups of tea per hour = 30x
David works for D hours this week.
Therefore number of weekly cups of tea = number of hours * cups of tea per hour
This is 30x * D = 30Dx
For Andrew, it is similar
30Ay
Because Andrew made an additional 10 cups, then it is 30Ay + 10
(cups of coffee this week)
