Atruck can be rented from company a for $40 a day plus $0.30 per mile. company b charges $20 a day plus $0.70 per mile to rent the same truck. find the number of miles in a day at which the rental costs for company a and company b are the same.

50 Miles

Step-by-step explanation:

The equations would be Company A- y=40+0.30x and Company B- y=20+0.70x

When you substitute x for 50 you get A- 40+0.30(50)=40+15=55$ and for B- 20+0.70(50)=20+35=55$ therefor the total miles to be the same for both would be 50 miles.

plants store their excess carbohydrate in the form of starch so that it could be used as energy source later on. the excess carbohydrate is converted into starch in the plastid i.e. chloroplast & this process occurs in the presence of sunlight. it is an insoluble polymer of glucose which gets stored in cell organelles named as amyloplasts. in some plants, starch is also stored in roots and embryos.
