Answer:
They are both wrong
Step-by-step explanation:
exponents are repeated multiplication. so it would be 2*2*2*2... that 28 times.
Steve: y=250-25x. This is because Steve starts with $250 and for every week, which is your unit of time and is represented by variable x, he spends $25. Chelsea: y=30+30x. Chelsea starts with $30, so the 30x is adding to your constant.
