The expression, (1.39)^w, reveals the weekly rate of increase in sales.

Using the properties of exponents, rewrite the expression to reveal the daily rate of increase in sales.

anonymous · Answer

$$(1.39)^w=(1.39^1/7)^7w \approx(1.048)^7w$$

anonymous · Answer

Therefore, the expression, (1.048)^7w, reveals the approximate daily rate of increase in sales for the store.
