The inequality that can be used is:
0.50d + 1 ≤ 10
where d is the number of doughnuts Shirley can buy and 1 is the cost of the carryout box.
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?
