I would rather look at a frequency table because the exact numbers would be shown and it could tell you by how much and how frequently they’re increasing . A bar graph could do the same , but sometimes they could be grouped so it wouldn’t tell you the exact number .
You would need to write at least 11 checks for the second one to be a better option.
Since the first has a lower base cost, we know it is cheaper to start. So, we have to find out when they become even. To do so, we need an equation for both banks. We can model the first one using 5 + .25x (where x is the number of checks) and the second as 6 + .15x. Now we can set them equal to find when they are even.
5 + .25x = 6 + .15x -----> subtract 5 from both sides
.25x = 1 + .15x -----> subtract .15x from both sides
.10x = 1 -----> multiply both sides by 10
x = 10
Since they are even at 10 and better for bank 1 before that, they are all better for bank 2 afterwards.
Hey there,
So when you round a number the rule is if it is less than 5 you round down and of it is more than 5 or equal to 5 you round up right?
So the highest number it could have been is 10.019 because that’s the highest number you round up to get 10.2
Hope this helps
Answer:
y = -7
Step-by-step explanation:
3.35 - 3.10 = .25
.25/3.35 = .0746
.0746*100 = 7.46 or 7.5 rounded
