The demand for widgets (QX) is given by the following equation:
QX = 425-PX¡V1.5PW¡V1.25PG+0.8PY+0.1 M
where QX= number of units of widgets sold per week
PX = the price of widgets = 400
PW = the price of woozles = 50
PG = the price of gadgets = 80
PY = the price of whatsits
To find the demand for widgets (QX) using the equation provided, you need to substitute the given values for PX, PW, PG, and PY into the equation.
Given values:
PX = 400
PW = 50
PG = 80
PY = ? (The price of whatsits is missing in the question. Please provide the value of PY in order to calculate the demand for widgets accurately.)
Once you have the value for PY, you can then plug it into the equation and calculate the demand for widgets QX.
