In my opinion I think that you have to multiply 13.55 by 8 ounces to find how much she needs to pay.
Answer:
x = -1/7 or -0.14285 - in decimal form
Step-by-step explanation:
8x + 5 = -6x + 3
8x + 6x = 3 - 5 { change side }
14x = -2 { basic addition and subtraction }
x = -2/14 { changing sides }
x = -1/7 { simplified }
45 minutes equal to 2700 seconds.
You will have approximately $257 at the end of 8 years.
