Answer:

  • Susan paid $2220 more

Step-by-step explanation:

<u>Use the interest formula:</u>

  • I = Prt, where P - amount of loan, r- interest rate, t- time in years

<u>Robert:</u>

  • I = 30000*(4.9/100)*4 = 5880

<u>Susan:</u>

  • I = 30000*(4.5/100)*6 = 8100

<u>Difference in amounts of interest:</u>

  • 8100 - 5880 = 2220

Susan paid $2220 more

IgorC [24]

Answer:

20

Step-by-step explanation:

GIVEN: Tina, Sijil, Kia, vinayash Alisha and shifa are playing game by forming two teams Three players in each team.

TO FIND: how many different ways can they be put into two teams of three players.

SOLUTION:

Total number of players =6

total teams to be formed =2

total players in one team =3

we have to number of ways of selecting 3 players for one team, rest 3 will go in other team.

Total number of ways of selecting 3 players =^6C_3

                                                                      =\frac{6!}{3!3!}

                                                                     =20

Hence total number of different ways in which they can be put into two different teams is 6
