Answer:
it would be y=50+25x
Step-by-step explanation:
There is an extra $25 per room, and since we dont know how many rooms she has cleaned, we can use x to represent that amount. So for x amount of rooms, it will be an extra $25
2+5(x+3)- (2x-7)(x+2)
7(x+3)- (3x+4x-7x-14)
(7x+21)-(7x-7x-14)
(7x+21)-(14)
7x+21-14
=7x+7

12.75
12.75 rounded to the nearest tenth is 12.8, and 12.74 won't work because it will round to 12.7.
Therefore, 12.75 is the smallest possible number.
6.75
10.00-3.25= 5.75
the first pieces of information are irrelevant
