At a used bookstore, Cindy bought a paperback book for $1.75 and some children's books for $0.75 each. She spent a
total of $5.75. Which equation will find how many children's
books Cindy bought?
A. 1.75 -0.75x = 5.75
B. 1.75 +0.75x = 5.75
C. 1.75X + 0.75 = 5.75
D. 1.75% - 0.75 = 5.75

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)
