1. **State the problem:** Newton recycled 79,270 tons of material this year, and the amount increases by 8% each year. We want to find how much material will be recycled 10 years from now.
2. **Formula used:** For exponential growth, the amount after $t$ years is given by:
$$ A = P(1 + r)^t $$
where:
- $P$ is the initial amount,
- $r$ is the growth rate (as a decimal),
- $t$ is the number of years,
- $A$ is the amount after $t$ years.
3. **Identify values:**
- $P = 79270$
- $r = 0.08$
- $t = 10$
4. **Calculate:**
$$ A = 79270(1 + 0.08)^{10} = 79270(1.08)^{10} $$
5. **Evaluate the power:**
$$ (1.08)^{10} \approx 2.1589 $$
6. **Multiply:**
$$ A \approx 79270 \times 2.1589 $$
7. **Intermediate step with cancellation (conceptual):**
$$ A = \cancel{79270} \times 2.1589 $$
8. **Final calculation:**
$$ A \approx 171,095.1 $$
9. **Answer:** Newton will recycle approximately **171,095.1** tons of material 10 years in the future.
