1. The problem asks to convert a Mayan number into its equivalent Base-10 number. 2. Mayan numbers are written vertically with each row representing a place value increasing by powers of 20 from bottom to top. 3. Each dot represents 1 and each bar represents 5. 4. Let's identify the values in each row from top to bottom: - Top row: 4 dots = $4 \times 20^3$ - Second row: 3 bars = $3 \times 5 = 15$ so $15 \times 20^2$ - Third row: 3 dots = $3 \times 20^1$ - Bottom row: 1 dot = $1 \times 20^0$ 5. Calculate each place value: - $4 \times 20^3 = 4 \times 8000 = 32000$ - $15 \times 20^2 = 15 \times 400 = 6000$ - $3 \times 20 = 60$ - $1 \times 1 = 1$ 6. Add all values: $$32000 + 6000 + 60 + 1 = 38061$$ 7. Therefore, the equivalent Base-10 number is $38061$.
