Let the number of cards equal x.
Set up an equation for both companies, set equal to each other and solve for x.
0.10x + 12 = 0.12x + 10
Subtractb0.10x from both sides:
12 = 0.02x + 10
Subtract 10 from both sides:
2 = 0.02x
Divide both sides by 0.02:
X = 2/0.02
X = 100
100 cards would be the same price for both companies.
Answer:
(0, -1), (1, 0), (2, 1)
Step-by-step explanation:
I find this easier to do after multiplying the equation by -1:
y = x - 1
Pick any value for x, then subtract 1 from it to find the corresponding value of y.
Hi!
The first thing I would do is see how much the charity has to make to exceed its goal. To do that, I would subtract how much they've already made from their goal.
1200 - 750 = 450
Now, since each ad provides 25 dollars, and the charity wants to exceed its goal, add 25 to 450, to get 475. (What they have to make to exceed their goal)
Now, just find how many ads must be made, or how many 25 dollars, go into 475, by dividing 475 by 25.
475/25 = 19 ads
Of course, if you get this question wrong and instead its 18 because your teacher stated they weren't supposed to exceed the goal and instead just meet it, you can question their wording of the problem.
Hope this helped!
Answer:
3 cups of flour.
Step-by-step explanation:
To solve this problem you would add 3 1/3 and 1 2/3 which would give you a total of 5. Then you would subtract 5 from you total 8 cups of flour which will give you a difference of 3 cups of flour left.
