Amy would have spent $22.5 on her books (assuming you meant $10 total, not $10 per book)
Bottom answer 2/5 and 7/8
Answer:
x = 1
Explanation:

Rule: log(a) + log(b) = log(ab)

cancel out log on both sides

relocate constant variable

take 3 as a common factor

divide both sides by 3

middle term split

factor common terms

collect into groups

set to zero

relocate variables

There must be a positive solution for log, so the solution is only x = 1
Answer:x-24
Step-by-step explanation:
Solve for xby simplifying both sides of the equation, then isolating the variable.
