1. **State the problem:**
We want to find out if depositing $70 monthly into an account with an APR of 7% compounded monthly for 15 years will accumulate at least $70,000.
2. **Formula used:**
We use the future value of an ordinary annuity formula:
$$A = P \times \frac{(1 + r)^n - 1}{r}$$
where:
- $A$ is the amount accumulated after $n$ periods,
- $P$ is the payment per period,
- $r$ is the interest rate per period,
- $n$ is the total number of payments.
3. **Identify values:**
- $P = 70$
- APR = 7% annually, so monthly rate $r = \frac{0.07}{12} = 0.005833333$
- Number of months $n = 15 \times 12 = 180$
4. **Calculate $(1 + r)^n$:**
$$ (1 + 0.005833333)^{180} = 1.005833333^{180} $$
Using a calculator, this equals approximately $2.849006$.
5. **Calculate the numerator:**
$$ (1 + r)^n - 1 = 2.849006 - 1 = 1.849006 $$
6. **Calculate the fraction:**
$$ \frac{1.849006}{0.005833333} = 316.785 $$
7. **Calculate the future value $A$:**
$$ A = 70 \times 316.785 = 22174.95 $$
8. **Interpretation:**
The amount accumulated is $22174.95$, which is less than the goal of $70000$.
**Final answer:**
A. No, because the amount that will be in the college fund, $22174.95$, is less than the goal of $70000$.
