Question

the first supermarket charges $.10 less for a can of orange juice than the second store. if the total cost of the two cans is $3.40, how much does the first supermarket charge?

Answer 1

Answer:

$1.65

Step-by-step explanation:

Equation:  (x -0.10) + x = 3.40

Substitute:  2x-0.10 = 3.40

add 0.10 on both side: 2x = 3.50

divide:  x =1.75

The second store charge $1.75 and the first store charged $0.10 less so it would be $1.65

$1.65 + $1.75 = $3.40 (total)
