Step-by-step explanation:
the x are the same, so jsut subtract y. 12 - Β -1 = 13
1. 35.50 increase 60% =
35.50 Γ (1 + 60%) = 35.50 Γ (1 + 0.6) = $56.80
2. 14.75 increase 45% =
14.75 Γ (1 + 45%) = 14.75 Γ (1 + 0.45) = 21.3875 = $21.39
3. 98.25 increase 7% =
98.25 Γ (1 + 7%) = 98.25 Γ (1 + 0.07) = 105.1275 = $105.13
4. 19250.95 increase 4.5% =
19250.95 Γ (1 + 4.5%) = 19250.95 Γ (1 + 0.045) = 20117.24275 = $20117.24
