Q:
A shop sells matching hats and scarves. The scarves
cost 1.5 times as much as the hats. Write two patterns
that could represent the costs of \( 1,2,3,4 \), and 5 hats
and scarves. List the first 5 terms of each pattern. Then
explain how to find the cost of 6 hats and scarves,
using the patterns you wrote.
