6.Merline is a window cleaner. She uses the following formula to work out how much to
charge her customers:
C = 5 + 0.5g + f
In the formula, C is the charge in pounds, g is the number of ground-floor windows that
the house has, and f is the number of first-floor windows.
a How much does Merline charge for cleaning the windows of:
i a house with four ground-floor windows and four first-floor windows?
ii a house with three ground-floor windows and three first-floor windows?
iii a bungalow with seven ground-floor windows?
b Merline charges £11.50 for a house with four first-floor windows. How many
ground-floor windows does the house have?
