Richard goes to the electronic store. he buys two memory cards that cost $8.99 each and three packages of batteries that are on sale for $7.49 each. he also buys a case for his cell phone for $2.99 and a wireless headset for $29.99. what is the total cost of richard's items, before sales tax?

$8.99x3+7.47x3+2.99+29.99=73.37 so the total cost for all of the items $73.37. Hope this helps :)

y = 3(- 2) = 3 × - 2 = - 6

the point on the graph is (- 2, 6)
