Equation: 50 is greater than or equal to 45 + .5(x)
x = amount of pictures you can send without going over your budget
subtract 45 from both sides. you are left with: 5 is greater than or equal to .5(x)
multiply both sides by 2. you are left with: 10 is greater than or equal to x
Answer: 10 is greater than or equal to x
The Answer To Your Question Would Be 12
To find the box answer, you can divide y by x:

You can check every pair, bit I'm going to show you the first 2 as an example:

So 3/2 is the answer!
Remark
2015 is an odd numbered year. It is not a leap year. It has 365 days in it.
Equation
Total deaths = deaths / day * number of days
Givens
Total deaths = 32800
deaths / day = ???
number of days = 365
Sub and solve
32800 = x * 365 Divide by sides by 365
32800 / 365 = x
x = 89.86 deaths per day.
Problem
Do you round up, down or leave the number as it is?
I would round up 90 deaths per day.
Discussion
Just how much are you out?
Total deaths in a year (rounded) = 90 * 365
Total deaths in a year (rounded)= 32850 which is 50 too many
Suppose you round down
Total death/day = 89 * 365 = 39485 Rounding up is going to be better if you round at all.
Perhaps you should not round the answer at all and leave it at
89.86 <<<<< answer.
