10 sheets for a $2 means each costs $0.20
6 sheets for $0.60 means each costs $0.10
3 sheets for $0.60 means each costs $0.20
5 sheets for $1 means each sheet costs $0.20
So the answer is 6 sheets for $0.60 since that is the cheapest amount.
Hope this helps! Let me know if you need any further assistance!
Hi there!
Let's solve this problem step by step!
The sum of the angles measures 360°, which is given in the question.
We can also express the sum of the angles as a sum of variables. To do this we must add all the variables a.

Collect terms.

When we have this expression and the sum of the angles, we can set up and solve an equation.

Divide both sides by 6.

Therefore a = 60°

BC = 19.1-10.4 = 8.7
19) AB = BC = 8.7
20) CG = 30.6 -8.7 =21.9
21) AG = 8.7 +30.6 = 39.3
22) FG = DG (DG = 30.6-10.4-8.7) = 11.5
23) EH = 8.7 + 11.5 +8.7 = 28.9
24) EJ = 8.7 + 11.5 + 21.3 = 41.5
