Adrian has saved up all his money from his allowances, which is $5 a week for the past year, his birthday, where he received $30 from his grandma, and the 5 quarters he found at the park so that he can buy a new bike. The bike is originally $230, but is on sale right now for 40% off the original price. Then in the mail he found two coupons, one that says "$20 additional off sale items" and the other that says "20% additional off sale items". Which coupon should he use to get the best deal on the bike and why is it the better deal?

a complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a solution of the equation x2 = −1. because no real number satisfies this equation, i is called an imaginary number. has no real solution, since the square of a real number cannot be negative.

answer: bea's uncle is 25 years old.

step-by-step explanation:
