In other words, Lynn paid 8 units, and Karen paid 5 units + $10.
The difference is 3 units - $10.
3 units - $10 =$14
Solve for 1 unit.

Question 11
For figure number N,
The number of triangular faces = the Nth even number
The number of rectangular faces = the odd number after the Nth odd number
(a) For N = 10
Number of triangular faces = 10th even number
= 20
Number of rectangular faces = odd number after the 10th odd number
= odd number after 19
= 21
(b) 51 is the 26th odd number. So the figure number is 25.
