To determine the value of the painting after 70 years with an annual increase of $1.20, you can use the following formula:
\[ \text{Future Value} = \text{Current Value} + (\text{Annual Increase} \times \text{Number of Years}) \]
Given:
- Current Value (Current Worth) = $135
- Annual Increase = $1.20
- Number of Years = 70
Now, plug in the values:
\[ \text{Future Value} = 135 + (1.20 \times 70) \]
First, calculate the total increase over 70 years:
\[ 1.20 \times 70 = 84 \]
Now add this increase to the current value:
\[ \text{Future Value} = 135 + 84 = 219 \]
Thus, the painting will be worth $219 after 70 years.
