Answer:
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
