Simple Interest Rate Formula: A = P(1 + rt)

P is principle amountr is ratet is time

Step-by-step explanation:

Step 1: Define

Identify variables

P = 8500

r = 4.75% = 0.0475

t = 6

Step 2: Find Interest

Substitute in variables [Simple Interest Rate Formula]:                                 A = 8500(1 + 0.0475 · 6)(Parenthesis) Multiply:                                                                                      A = 8500(1 + 0.285)(Parenthesis) Add:                                                                                            A = 8500(1.285)Multiply:                                                                                                             A = 10922.50

1) Jeremy found 80% of the cards. Tim found 41/45 of the cards. 41/45=91%

So Tim found more cards.

2) 20% of 45 is 9,  so John took 9

Pauline took 36.

36+9=45, so there are no more apples on the tree.

45 is more than 9, so Pauline took more apples.

3) Henry got 20/45.

Nelly got 55%.

20/45 is about 44%

55>44, so Nelly has a better rated movie.

4) David found 15 pieces.

15/45=33%

Henry found 40% of the pieces.

40>33, so Henry found more pieces.

5, BONUS)

Carla, 9/45, so 20%

Leonard, 18/45 so 40%

Henry, 18/45, so 40%
