Her total should be 84. You have your 30 dollars that will not change which you need to add to the amount of every visit. To find the amount for each time she went you have to do 3*18 because she went 18 times for 3 dollars each. Your answer to 3*18 should be 54. You now have to add those 54 to the 30 per month. 30+54. That should be 84
I think you divde the fractions
Step-by-step explanation:
<u>The line of best fit given:</u>
<u>It is given in the slope-intercept form:</u>
- y = mx + b, where m- slope, b - y-intercept
The slope is this situation is m = 0.404 cm and it represents the average growth rate of the plant in one day.
It seems reasonable but without means of control it is difficult to trace the growth while still under the ground, during the first 13-14 days.
