Answer:
She will earn $392 in interest over this 4-year period.
Step-by-step explanation:
The formula for simple interest is i = p*r*t, where p is the principal, r is the interest rate as a decimal fraction, and t is the number of years.
Here i = $1400(0.07)(4) = $1400(0.28) = $392
She will earn $392 in interest over this 4-year period.
