Answer:
3.59
Step-by-step explanation:
Take the price of gas to be "P" on Monday and then went up by 5%. So on Tuesday, it was (1+ 0.05)P= 1.05P on Tuesday. It went down by 2% so was (1- 0.02)(1.05P)= 0.98(1.05P)= 1.029P on Wednesday. That was $3.59 so 1.029P= 3.59.
Solve for P by dividing both sides by 1.029.
