"True: the product of two polynomials will be a polynomial regardless of the signs of the leading coefficients of the polynomials. When two polynomials are multiplied, each term of the first polynomial is multiplied by each term of the second polynomial."
58×.20=11.60 58.00+11.60= 69.60 your total cost is 69.60 to leave your tip on top of the bill
Step-by-step explanation:
any time you want a percentage of a number you take your number in this case 58.00 times whatever percentage in this case 20% so 58×.20 =11.60 then you take your total plus the amount you come up with for the tip 58.00+11.60=69.60
