The Hu family goes out for lunch, and the price of the meal is $44. The sales tax on the meal is 6%, and the family also leaves a 15% tip on the pre-tax amount. What is the total cost of the meal?

56.70

Step-by-step explanation:

45x0.06= 2.70

45x0.20=9

45+2.70+9= 56.70

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.
