Answer 1

7) A. $96

8) A. $216

9) C. $86

10) E. $88

Explanation:

7) Clothes = hat (3%) + sneakers (21%)

Hat: $400 * 3%(0.03) = $12

Sneakers: $400 x 21%(0.21) = $84

$12 + $84 = $96!

8) Find snowboard percentage by:

100% - (The all revealed percent)

= 100% - (21%+14%+8%+3%) = 51%

= $400 * 51%(0.51) = $216

9) Video games = 14%

= $400 * 41%(0.41) = $86

10)

Dvds: $400 * 8% = $32

Video games = $86

= $32 + $86
