A farmer's market sells grapefruit, strawberries, and avocados. They each have a different cost and are priced per box. Alyssa buys two boxes of strawberries
and three boxes of avocados and spends $23. Landon buys three boxes of
grapefruit and four boxes of strawberries and spends $19. Tina buys 7 boxes
of grapefruit and 5 boxes of avocados and spends $51. Find the missing
quantity below.

The answer is below

Step-by-step explanation:

Let x represent the price of grapefruits per box, y represent the price of strawberries per box and z represent the price of avocados per box.

The money spent by Alyssa who buys two boxes of strawberries  and three boxes of avocados and spends $23 is given by the equation:

2y + 3z = 23             (1)

The money spent by Landon who buys three boxes of  grapefruit and four boxes of strawberries and spends $19 is given by the equation:

3x + 4y = 19              (2)

The money spent by Tina who buys 7 boxes  of grapefruit and 5 boxes of avocados and spends $51 is given by the equation:

7x + 5z = 51              (3)

Solving equation 1, 2 and 3 simultaneously gives:

x = 3, y = 2.5 and z = 6.

Therefore the cost of grapefruits per box is $3, cost of strawberries per box is $2.5 and cost of avocados per box is $6
