Question

The cost of a hall rental for a wedding is $500. Each meal at the wedding will cost an additional $45.50

a) Write an algebraic expression equation for the total cost of the wedding.
b) Calculate how many people attended the wedding if the wedding cost totalled $3912.50.

Answer 1

a) 45.50p + 500

b) 45.50p + 500 = 3912.50

p = 70

Explanation:

p = number of people

$45.50 for a meal for each person, so:

45.50p

The constant is $500, so let's add that to the expression:

45.50p + 500
