Question 5, Page 148

$19.99 multiplied by 3 = 59.97

5% + 6% = 12%

1 + 12% = 1.12

59.97 multiplied by 1.12 = 67.1664 (66.57)

Question 7, Page 149

a)

First Year:

Divide 100 by 10 = 10.

10 new Caribou.

10 + 100 = 110

Second Year:

Divide 110 by 10 = 11

Mulitple 11 by 2 = 22
110 + 22 = 132 Caribou

b)

There wasn't a 30% increase because the second year, it is 20% off of the 10% in the first year (20% increase of the 110 caribou)

Question 6, Page 148 $38.25

Week 1:

$85.00 divided by 2 = 42.50

Week 2:

42.50 divided by 10 = 4.25

$42.50 - $4.25 = $38.25
