Answer:

(20)(30) + (15)(15) − 130

Step-by-step explanation:

Part A: (20)(30) + (15)(15) − 130

Part B (and maybe C. im not sure): Each keyboard is sold for $30 and there are 20 keyboards. So 20*30 is better than writing 30*30*30*30.....

There are 15 chargers and each one is sold for $15. So 15*15 is the answer.

The 130 has a minus (before it) because $130 was spent when they bought 20 keyboards and 15 chargers.
