Given that the received amount was $350 from a car wash, $337 from a bake sale, and $490 from a used equipment sale.
Also, the interest rate is 2.2 % and the time period is 3 years.
Thus, the total amount is as follows:

Next, the accumulated amount can be calculated as follows:

Further, solve the obtained result as follows:

Thus, the league will have $1256.40 in their account after 3 years.
x² - x + 4x - 4 → D
Expand using the FOIL method
F → multiply First terms → x and x = x²
O → multiply the Outer terms → - 1 and x = - x
I → multiply the Inner terms → 4 and x = 4x
L → multiply the last terms → 4 and - 1 = - 4
(x + 4)(x - 1) = x² - x + 4x - 4
I believe the answer would be 24786cf
