Acharity bingo game costs $2 per round and has a $13 entry fee for an adult. it costs $3 per round and a $10 entry fee for a child. for how many rounds of bingo are the costs the same for an adult and a child? a 2 b 3 c 4 d 5

For this case we have to:

x: Be the variable that represents the number of adult rounds

y: Be the variable that represents the number of rounds of children

We want to know for what amount of rounds bingo costs are the same for adults and children.

Adult costs = 2x + 13

Child costs = 3y + 10

Matching:

We want the same number of rounds, x = y:

Thus, for 3 rounds the costs are the same.

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.

answer: x=3 and y=4
