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.

Q:
System B
\( 2 x+y=6 \)
\( -2 x-y+6=0 \)
Q:
7. The equation for a tile pattern is \( y=\frac{2}{3} x+12 \).
Find the total number of tiles for \( f(15) \) of this
pattern.
Q:
