5a(b-c)=d. Here, we are trying to isolate the variable b.
Divide both sides by 5a: b-c=d/(5a)
Add c to both sides: b=
Each pencil cost $2.
Explanation: She had $24 before buying the pencils and after she had $10. 24-10=14 so the total she spent on pencils was $14. She bought 7 pencils so you divide 14 by 7 (14/7=2) which equals 2. So each pencil cost $2.

Answer: D. 12,330 phones
Step-by-step explanation:
First remove the fixed cost from the operating budget so that the variable cost that can be spent on each phone is known in total:
= 951,615 - 225,378
= $726,237
With each phone costing $58.90, the total number of phones that can be produced is therefore:
= Variable budget / Variable cost per phone
= 726,237 / 58.90
= 12,330 phones
