If you are buying an item at a store for a price of $21, and there is a 8.7% tax added on top, what would be the total amount due at the register to the nearest cent

Since opening night, attendance at play a has increased steadily, while attendance at play b first rose and then fell. equations modeling the daily attendance y at each play are shown below, where x is the number of days since opening night. on what day(s) was the attendance the same at both plays? what was the attendance? play a: y = 8x + 191 play b: y = -x^2 + 26x + 126

Solve this system of equations. 12x − 18y = 27 4x − 6y = 10

What’s 8y+48 and factor each expression completely
