An animal shelter spends $3.50 per day to care for each cat and $8.50 per day to care for each dog. madison noticed that the shelter spent $85.50 caring for cats and dogs on monday. madison found a record showing that there were a total of 13 cats and dogs on monday. how many cats were at the shelter on monday?

There would be 5 cats on Monday.

Step-by-step explanation:

3.50c+8.50d=85.50

c+d=13

Solve for c.

c+d=13

  -d  -d

c=13-d

Plug it in.

3.50(13-d)+8.50d=85.50

45.50-3.50d+8.50d=85.50

Add like terms.

-3.50d+8.50d=5d

Solve for d.

45.50+5d=85.50

-45.50       -45.50

5/5d=40/5

d=8

Plug in.

3.50c+8.50(8)=85.50

3.50c+68=85.50

         -68  -68

3.50/3.50c=17.50/3.50

c=5

Check your answer.

3.50(5)+8.50(8)=85.50

17.50+68=85.50

85.50=85.50

Therefore

c=5

d=8

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.
