Question

Answer following question, see if you have got the concept of how to set up an alegebric equation. You have to buy two dozen eggs priced at $10, three breads (each bread is $5), and five bottles of juice (each bottle is $8). How much money you will need to take to store. Let's E represent egg, B for bread, and J for a bottle of juce 1) What is the algebric expression? 2) solve the expression by plugging cost of each item to get total price. 3) How much do you need to take to store?

Answer 1

Answer: (1) 2E+3B+5J (2) $75 and (3) One need to take $75 to the store

Explanation: (1) Since, E represents Eggs, B represents bread and J represents juice and there are two dozens of eggs, three breads and 5 bolltes of juice. Therefore, totoal amount is expressed as

2E+3B+5J --------------------------------------------- (1)

This represents the algebraic expression for the total shopping.

(2) Now, plugging price of each items as E=$10, B=$5 and J=$8 into eqn 1,

Total price=2E+3B+5J=2*10+3*5+5*8=20+15+40=$75

(3) One need to take $75 to the store.
