Not sure what answer your needing so here is a breakdown of the amounts.
3 bracelets times $5 equals $15
How much is each necklace?
Subtract $15 from $40 you have $25 left. Then you divide $25 by 3 you get each necklace costs $8.33 so three necklaces cost $24.99
When you add $15 from the bracelets and $24.99 from the necklaces your total is $39.99 that’s why Megan gave the clerk $40

Scientific notation means to write the answer in standard form. standard form helps you to express numbers that are too big or too small to be conveniently written in decimal form.
so for this case, it will be 4.571×10^-4.
when the number is decimal, you move the dot to the right and it will always be multiplying 10 to the power of a negative power.
72 days
there are 720 ounces total (convert 45 pounds to 720 ounces)
divide that by the 10 ounces per day and get 72 days
