Do you need the expanded notation form, or expanded factor form?
Answer:
12 books
Step-by-step explanation:
Since she has $15 and books come in a pack of four for $5, we can divide her money by the cost to see how many she can get ($15/$5) which gets us 3. but we have to remember the books come in a pack of four so we must multiply 3x4=12 books.
Brand b is 2 cents cheaper than brand a because it is 14 cents per ounce and brand a is 16 cents per ounce you do 1.68 divided by 12 and 1.28 divided by 8
-3(x+(3))^2-4 is the answer
.15% translates to
.0015, and "of" means to multiply. so .0015 multiplied with 43 is
.0645
