Answer:

At The given rate, the area of floor that Jessica can wax is 33.3 m²

Step-by-step explanation:

Given as :

The area of floor waxed = 20 square meters

The time taken to waxed 20 square meters floor = $\dfrac{3}{5}$ hours

Let The area of floor waxed per hour = A m²

<u>Now, Applying unitary method</u>

∵ In $\dfrac{3}{5}$ hours, The area of floor waxed = 20 m²

∴ In 1 hour , The area of floor waxed = $\frac{20}{\frac{3}{5}}$ m²

I.e In 1 hour , The area of floor waxed = $\frac{20\times 5}{3}$ m²

Or, In 1 hour , The area of floor waxed = $\dfrac{100}{3}$ = 33.3 m²

Or, In 1 hour The area of floor waxed = A = 33.3 m²

Hence, At The given rate, the area of floor that Jessica can wax is 33.3 m² Answer

$2,500 • 7.5% (or 0.075) = $187.50 (for one year).

For two years, the interested added onto the original price is $375 because $187.50 • 2 (years) = $375.

$2,500 + $375 = $2,875

The total of the cost of the surgery and the interest is $2,875.

Hope this helps! ❤️
