A store is having a sale on jelly beans and almonds. For two almonds of jellybeans and 5 pounds of almonds the total cost is $10. For 8 pounds of jellybeans and 3 pounds of almonds, the total cost is $23. Find the cost for each pound of jellybeans and each pound of almonds

The answer to your question is almonds = $1, jelly beans = $2.5

Step-by-step explanation:

Data

2 pounds of jelly beans and 5 pounds of almonds = $10

8 pounds of jelly beans and 3 pounds of almonds = $23

jelly beans = j

almonds = a

Process

1.- Write two equations to solve this problem

              2j + 5a = 10                      Equation l

              8j + 3 a = 23                     Equation ll

2.- Solve the system of equations by elimination

-Multiply equation l by -4

              -8j - 20a = -40

               8j + 3 a = 23

-Simplify

                0  - 17 a = -17

                           a = -17/-17

                           a = 1

-Find j

             8j + 3(1) = 23

             8j + 3 = 23

             8j = 23 - 3

             8j = 20

               j = 20/8

               j = 2.5

3.- Conclusion

The pound of almonds costs $1 and the pound of jelly beans costs $2.5

the cost of each pound of jellybeans is $2.5

the cost of each pound of almonds is $1

Step-by-step explanation:

Let x represent the cost of each pound of jellybeans.

Let y represent the cost of each pound of almonds.

For two pounds of jellybeans and 5 pounds of almonds the total cost is $10. It means that

2x + 5y = 10- - - - - - - - -1

For 8 pounds of jellybeans and 3 pounds of almonds, the total cost is $23. It means that

8x + 3y = 23- - - - - - - - - -2

Multiplying equation 1 by 4 and equation 2 by 1, it becomes

8x + 20y = 40

8x + 3y = 23

Subtracting, it becomes

17y = 17

y = 17/17

y = 1

Substituting y = 1 into equation 1, it becomes

2x + 5 × 1 = 10

2x + 5 = 10

2x = 10 - 5 = 5

x = 5/2 = 2.5

a) 7x=7

step-by-step explanation:

answer:   expression= p+p*d%

price reduction + sale price = $625

sale price: $p+$p*d%

where d% is the percentage of discount

step-by-step explanation:

original price = p

price went down by $150 price reduction $p*d%

sale price= $ 475

therefore the price before sale is: $625

and the expression that shows the price before sale is: p+p*d%
