Answer: the first option! this is because one of the equations, x = y-4, is telling you what x equals. so in order to solve the equation, you need to substitute that into the x in the second equation
Let's not think about the problem, let's think about the fractions and dividing. We're are trying to find how many sets of 3/44 are in 3 3/4. We need to divide. Using keep change and flip, we can divide successfully.
Let's make sure the first fraction is improper.
15/4÷3/44=?
Keep, Change, and Flip.
15/4×44/3
660/12
Let's simplify.
55.
So Nicole can play 55 rounds.
The only restraints on profit result from the restriction on the domain which in turn place a restriction on profit.
0≤k. Knives sold cannot be negative.
So the range of profit or p is:
p=[-500, +oo)
Profit increases as the number of knives sold increases. $200 more profit is gained by each sale of a knife.
4000=200k-500
4500=200k
k=22.5
Since k is for knives sold, it must be an integer value, so a $4000 profit is not possible. At 22, p=3900 and at 23, p=4100
