A doughnut shop charges $0.50 for each doughnut and $1 for a carryout box. Shirley has $10 to spend. Which inequality can be used to find d, the number of doughnuts she could have bought if she also wants them in one carryout box?
A) 0.50 + 1d ≥ 10
B) 0.50 + 1d ≤ 10
C) 0.50d + 1 ≥ 10
D) 0.50d + 1 ≤ 10
* I think it is d but I'm not sure*
