Next, you will assume that one shirt would cost $6.33.
Finally, Multiply by 4 to get the amount of four shirts.
To understand the algebra, go through the following equations below:
- First the thing to note is that the top square is the square of the bottom square: Stage 1: 1 &
, stage 2 = 2 &
, stage 3 = 3 & 
- Second image: Just add the two values above to get the total of tiles needed. For stage 5: 5 +
= 30, Stage 12: 12 +
= 156
Part B
- First equation : y =
+ n
- second equation: y = n + (n*n)

We know that
<span>the length of Q is 25% more than the length of p
</span>so
length Q=1.25*40--------> 50 cm
<span>the area of Q is 10% less than the area of p
Area Q=50*y
Area P=40*x
so
50*y=0.90*[40*x]---------> 50*y=36*x-------> x/y=50/36---> 25/18
the answer isthe ratio </span><span>
x:y is</span><span>
25:18</span>
