is this correct I2*100+3*10I=

I200+30I=I230I

which is equal to 230 (no absolute signs)

If a bag of chips has a serving size of 1 oz. and serving per container is 7. If the bag of chips costs 0.99, approximately how much does one serving of chips cost? would I start out by

99/7

No, the expression you have provided is not correct.

To analyze the correctness of the expression, let's break it down step by step:

I2 * 100: This implies multiplying the variable "I" by 2 and then multiplying the result by 100. So, the expression becomes 200I.

3 * 10I: Here, you have 3 multiplied by 10 and then multiplied by the variable "I." Therefore, it becomes 30I.

So, combining both parts, the correct expression would be 200I + 30I, which simplifies to 230I.

Therefore, the correct form of the expression is 230I.
