I am pretty sure the answer to your question would be $160
Answer:
The square root of x will be evaluated first before the addition of 5. Hence (-3)^2 = 9 and 9 +5 = 14, as per your teacher's answer, which is correct. The answer would not be -4.
150 divided by 25 equals 6. 6 times 3 equals 18. This means that you will spend $18 on gas each week.
