Kendra is participating in a read-a-thon to raise money for her local library. One person donates $30, while another pledges $0.05 for each page she reads. If Kendra raises $40, she will earn a prize. To find the number of pages, n, she must read to earn her prize, Kendra wrote this equation. 30+0.05n=40
What is the best strategy for solving this equation?
A. Divide both sides by 0.05. Then add 30 to both sides.
B. Subtract 30 from both sides. Then divide both sides by 0.05.
C. Subtract 30 from both sides. Then multiply both sides by 0.05.
D. Divide both sides by 0.05. Then subtract 30 from both sides.
