For a certain strain of bacteria, `k\approx0.728` when `t` is measured in days. Using the formula `y=ae^{kt}`, write an equation for a petri dish with 10 bacteria.
How many bacteria will be in the dish after 1 week? Round to the nearest whole number.
How long will it take the 10 bacteria to increase to 675 bacteria? Round to the nearest whole number.
