Please write a pair of equations for each situation.
The math club sold calendars to raise money for new calculaors. Julio sold 6 desk calendars and 10 wall calendars for a total of $100. Tina sold 12 desk calendars and 4 wall callendarsfor a total of $88. Be sure to define your variables.
:
Let price of desk calendars =x
Let price of wall calendars =y
Then, Julio sold:
6x+10y=100
Tina sold:
12x+4y=88
:
With two equations and two unknowns you can find out that the desk calendars cost $5 and the wall calendars cost $7.
Happy Calculating!!!
