i answered part of this earlier
julie = 2
kelly = 5
lou = 12

19 x £22 = £418
Answer:
71 degrees
Step-by-step explanation:
its an isosceles triangle so those angles are equal. Draw it out if that helps you.
Let's say the price of one book is the variable x
Therefore, Alana is 5x and Petra is 4x
Angus bought 19x, but since he had a $10 discount, it is 19x-10
Combined, Alana and Petra is 5x+4x, but since it says Angus spent $5 more, it would be 5x+4x+5
Therefore, we get the equation:
19x-10=5x+4x+5
19x-10=9x+5
10x=15
x=15/10 or 3/2 which equals 1.5
Therefore, one book costs $1.5
