Assume that the price of a combo meal is the same price as purchasing each item separately. find the price of a pizza, a coke, and a bag of chips.

pizza: $4, coke: $3, chips: $2

Step-by-step explanation:

Lets make the price of a pizza=p a coke= k and a bag of chips=c

then we have the following equations

p+k+c=9

p+2k=10

2p+2c=12

Because p is common in all the equations we shall make it the subject of each equation.

p=9-(k+c)i

p=10-2kii

p=6-ciii

We then equate i and iii

9-(k+c)=6-c

9-k-c=6-c

putting like terms together we get:

9-6=-c+c+k

1 coke, k=$3

replacing this value in equation ii

we get  p=10-2(3)

p=10-6= 4

1 pizza, p=$4

replacing this value in equation iii

4=6-c

c=6-4

=2

a bag of chips, c=$2

Thus, a pizza, a coke and a bag of chips= pizza: $4, coke: $3, chips: $2

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.
