Answer:
D. n-3=45
Step-by-step explanation:
So we know that the sum is 45,
=45
Now we must know the order of the expression,
It says that 3 less than,
3 less than means it is being decreased by 3, so,
n - 3 = 45
Tiana sold 15 boxes and Jeremy and Keanu sold 10
60% of 25 = 15
25 - 15 is 10
This is the way I understand the problem.
4
let the number be x
so by the question , 2x+5=13
solving this we get ,
2x=13-5
2x=8
so x=4
