These will be your answer keys for Unit 3.
x + 5 = 12
12 - 5 = 7
x = 7
d + 7 = 20
20 - 7 = 13
d = 13
5 x 7 = 35
c = 35
10 - 2 = 8
m = 8
1/3(108) + 72 = 36 + 72 = 108
1/3t + 72 = t and t - 72 = 1/3t
(7 × 7) = 49 new coconuts, then 98 - 49 = 49
c = 49
Total Spent: 250 bottles × $6 = $1,500
Good Bottles Left: 250 − 14 = 236 bottles
Total Earned: 236 bottles × $18 = $4,248
Profit: $4,248 − $1,500 = $2,748
Tuesday Revenue: 85 sets × $24 = $2,040
Wednesday Sets: 85 + 42 = 127 sets
Wednesday Revenue: 127 sets × $24 = $3,048
First 5 Zones: 5 × 46 = 230 patches
Last 3 Zones: 3 × 62 = 186 patches
Total Patches: 230 + 186 = 416 patches
Remaining Patches: 416 − 174 cleaned = 242 patches
New Average: 242 ÷ 8 zones = 30.25 → 30 patches per zone (with 2 leftover patches)
Turtles: 4 groups × 6 turtles = 24 turtles
Total Turtles + Seals: 24 + 14 seals = 38 animals
Total Triggerfish: 38 × 3 = 114 triggerfish
Triggerfish Per Coral Head: 114 ÷ 6 coral heads = 19 triggerfish
