A change in supply versus a change in quantity supplied

The following calculator shows the supply curve for sedans in an imaginary market. For simplicity, assume that all sedans are identical and sell for the

same price. Two factors that affect the supply of sedans are the level of technical knowledge$-$in this case, the speed with which manufacturing robots

can fasten bolts, or robot speed$-$and the wage rate that auto manufacturers must pay their employees. Initially, the graph shows the supply curve

when robots can fasten $2,500$ bolts per hour and autoworkers earn $$25$ per hour.

Use the graph input tool to help you answer the following questions. You will not be graded on any changes you make to this graph.

Note: Once you enter a value in a white field, the graph and any corresponding amounts in each grey field will change accordingly.
