Hello Dafnemlp47vj7
The inequality for one week would be <u><em>13 = 2c + 3 </em></u>
.45x+.55x=200
Combine like terms
1x=200
So x is 100
Or you can do 45%+55%=100%
And 100% of 200 is 200
It will be 6 cause it is going by 1+ 1,2,3,4,5,6 (if it was 1,3,6,9, it will be 12 cause it is going by 3+) so answer is 6
I think it is the tens because the first is ten thousand, second is thousand, third is hundreds and last is units ones
