Question

Transcribed Image Text:The demand for ACME Q-bits is given by the function q = f(Y,p), where:
- **q** = monthly demand for ACME Q-bits (measured in thousands of Q-bits)
- **Y** = average monthly income in the Q-bit market (measured in thousands of dollars)
- **p** = price per Q-bit that ACME sets (measured in dollars)
When the average monthly income is $4500 and ACME's price is $35, the conditions are:
- q = 22
- ∂q/∂Y = 0.77
- ∂q/∂p = -0.64
If the average monthly income increases to $4700, by approximately how much can ACME increase their price while keeping demand for the product fixed at q = 22?
**Hint:** Use linear approximation.
