A tuxedo rental service charges 150$ flat fee for a suit plus 50$ Per additional day. Which equation correctly models the total cost of renting a tuxedo for x number of days

1-y=50x+150

2-y=50x-150

3-y=150x+50

4-y=50x

The answer would be "1". Because, since "per" is next to 50 it means that it's multiplied so that would start of with 50x then it says it already charges a flat fee of 150 so you add it to the 50x and get y=50x+150
