Someone pls do these 3 for me, its due in 20 minutes and my head hurts so bad right now :(

Answer:

1. Chloe has more money.

2. Dylan does <u>not</u> have enough money to buy 3 bags of candy.

3. Mikayla could get 4 pennies, 2 nickels, 2 dimes, and 2 quarters back in change.

Step-by-step explanation:

Penny = 1 cent

Nickel = 5 cents

Dime = 10 cents

Quarter = 25 cents

1. Chloe has 2 quarters(50 cents) and 3 dimes(30 cents). 50 + 30 = 80 cents

Haru has 5 nickels(25 cents) and 4 dimes(40 cents). 25 + 40 = 65 cents

2. If each bag costs $350(oddly enough). Dylan would need $1,050 to buy 3 bags of candy. Instead he only has $10. This means he would need $1,040 more dollars.

3. $5 - 4.16 = 84 cents in return

quarter(25) + quarter(25) + dime(10) + dime(10) + nickel(5) + nickel(5) + penny(1) + penny(1) + penny(1) + penny(1) = 84 cents

Approximately how much do i save per bottel of juice if i buy a pack of 8 rather than a pack of 6
Korolek [52]

Answer: Your question is missing information but this is what you do to answer your question step by step

B = Cost of 8 pack / 8 bottles  =  $ Cost of 8 pack/ 8 =$ ____ per bottle

A = Cost of 6 pack/ 6 bottles = $ Cost of 6 pack/ 6= $ ____ per bottle

then do a simple subtraction  A -B = savings

Step-by-step explanation:  Information is incomplete

if an 8 pack cost $16

If the 6 pack cost $15

All you do is a simple subtraction after calculations

Cost of 8 pack / 8 bottles  = $16/8 =$2 per bottle

Cost of 6 pack/ 6 bottles = $15/ 6= $2.50 per bottle

in my example  

You would save $ 0.50 per bottle by purchasing the 8 pack

What’s the answer to this?
jasenka [17]

Answer:

It would be the first option: Last week, Rosemary walked at a faster pace.

Step-by-step explanation:

Last week, the speed was d=3h, as for this week, her speed was d=2.5h.

No one knows how many hours she walked this week so we cannot say that she walked a greater distance.
