Answer:
The cost of one ft² of grass sod is $12 and the cost of one pot of ivy is $4.
Step-by-step explanation:
Step 1: Define your variables:
• Let the cost of one ft² of grass sod = g
,
• Let the cost of one pot of ivy = p
Step 2: Derive the equations
Pranav spent $196 on 12 ft² of grass sod and 13 pots of ivy.

Juli spent $76 on 4 ft² of grass sod and 7 pots of ivy.

Step 3: Solve the system of equations

Multiply the first equation by 1 and the second equation by 3:

Subtract:

Next, substitute p=4 to solve for g:

The cost of one ft² of grass sod is $12 and the cost of one pot of ivy is $4.
