Lisa buys a dozen apples and two oranges. Jeremy buys six apples. Oranges cost $1 each, and they spent $9 total. How could you define variables to find the cost of the apples and oranges?

Verified Answer :

2 oranges cost $2 . $9 - $2 = $7
then 12 apply of Lisa and 6 apples of Jeremy
= 18 ÷ 7 = 2.57. $2.57 for 6 apples
2.57 ÷ 6 = 0.43 each apple

Answer:

The cost of each apple is $0.39

The cost of each orange is $1

Step-by-step explanation:

Lisa buys a dozen apples and two oranges.

Let 'x' be the cost of each apple

and 'y' be the cost of each orange

Lisa buys a dozen apples and two oranges.

\(12x+2y\)

Oranges cost $1 each, so y=1

Jeremy buys six apples.  So 6x

Total amount spent is $9

\(12x+2+6x=9\)

\(18x+2=9\)

Subtract 2 from both sides

\(18x=7\)

Divide both sides by 18

x=0.39

The cost of each apple is $0.39

The cost of each orange is $1
