I believe it's D. The amount of money in the bag depends on how many quarters you have; therefore you would multiply the amount of quarters by their value (.25) to get the total amount of money.

vlabodo [156]
Answer: C

Work:

1) Change the Mixed number into an improper fraction
3 x 8 = 24
1+24 = 25/3

2) Get both fractions on equal terms. Find the Greatest Common Denominator. In this case, it’s 24. Multiply by what you need to get 24. 8x3=24 and 12x2=24

3) Multiply Accordingly
25/8 x 3 = 75/24
7/12 x 2 = 14/24

4) Subtract and change back to Mixed Number
75-14 = 61
61/24 = 2 13/24

88.6*2628000 = 232,840,800

He or she has 232,840,800 beats in five minutes.

An electrician needs 18.25 feet of wire for each outlet she installs. How man can she install with a 50 ft spool of wire?
jolli1 [7]

Answer:

2

Step-by-step explanation:

Ok, so if we know how much wire is needed for one outlet, we must figure out how many 18.25s fit into 50 ft of wire.

18.25*2=36.5

18.25*3=54.75 which is over 50 so it cannot possibly be more than 2.
