Answer provided by our tutors
let 's' represent the number of spoons and 'f' represent the number of forks
total costs:
1.7f + 1.3s
the price of spoons is unknown, so let 'p' represent the price of spoons, then total revenue is:
5.4f + ps
37.90 = 1.7f + 1.3s
147.20 = 5.4f + ps
this leaves us with two equations and three unknowns...
...answering this question requires knowing the price at which spoons are sold
