A town's market for dog-grooming appointments consists only of Salon A, Salon B and Salon C. The table shows the number of appointments each salon is willing and able to supply each week before any salon changes its equipment.
| Price per appointment | Salon A | Salon B | Salon C |
|---|---|---|---|
| £30 | 18 | 22 | 15 |
| £38 | 24 | 28 | 20 |
After the price has risen to £38, Salon C installs faster drying equipment. With all other conditions unchanged, Salon C is then willing and able to supply 27 appointments each week at £38. The plans of Salon A and Salon B are unchanged.
Calculate the change in weekly market quantity supplied when the price rises from £30 to £38, before Salon C installs its new equipment.
Explain whether the change you calculated in (a) is a movement along the market supply curve or a shift of the curve.
Explain the effect of Salon C's new equipment on market supply.
