Answer: $120
Explanation To find the interest earned using the simple interest formula, use: Simple Interest = 𝑃 × 𝑟 × 𝑡 where: P is the principal amount ($1200), r is the annual interest rate (5% or 0.05), t is the time in years (2 years). Substitute the values into the formula: Simple Interest= 1200×0.05×2 Calculate: Simple Interest= 1200×0.05=60 Simple Interest= 60×2=120
Answer: 8:5
Explanation A/B = 2/3 B/C = 3/4 A/D = 4/5 We can start by finding the relationship between B and D: B/A = 3/2 (inverse of A/B) A/D = 4/5 Multiplying these two fractions, we get: B/D = (3/2) × (4/5) = 12/10 = 6/5 Now, we can find C/D: C/D = (C/B) × (B/D) = (4/3) × (6/5) = 8/5
