JO. Jeff buys 3 boxes of cereal for $2.99 each a gallon of mik for $4.98 and 4 bananas for $0.50 each. If has a 20% off his
Total bill coupon and he pays with a $20.00 bil, how much change
will he get back?

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11

this linear equation would have just one solution.

step-by-step explanation:

the reason why this would have one solution is that it is an expression with just one variable. since that variable is not raised to a power, it will always have just one solution.
