An online electronics store bought 20 keyboards and 15 phone chargers for $130 and then sold each keyboard for $30 and each phone charger for $15.

Part A: Which expression represents the amount of money the store made?
(20)(30) + (15)(15) − 130
(20)(15) + (15)(30) − 130
(20)(30) + (15)(15) + 130
(20)(15) + (15)(30) + 130

Part B: Explain why your answer to Part A is correct.

Part C: What is the value of the expression you chose in Part A? Show each step of your work.

Help plsss

Part A =
The first answer choice.

Part B -
This is because we are selling each keyboard for 30 dollars and selling each charger for 15$. Since we are told the amount of keyboards and chargers we are selling, we have to multiply that amount by the amount we are selling for each item. So, we have to do 20 x $30 to find out how much we made from selling keyboards, and 15 x $15 to find out how much money we made from selling chargers. However, we have to subtract $130 from our earning to find out how much we profited. This is because we spent $130 on 20 keyboards and 15 chargers, so we have to subtract it from our earnings to find out how much money we profited.

Part C-
20 x 30 + 15 x 15 - 130
We do 20 times 30 and 15 times 15, leaving us 600 + 225 - 130.
Then we do 600 + 225 leaving us with 825 dollars.
Finally, we subtract 825 by 130 leaving us with a total of 695 dollars.
