Question

at the craft store, lisa bought 3 clay blocks and 2 molds for $15.50. Tony bought 6 clat blocks and 1 mold for $19.00. Write and solve a system of equations to find the cost of each clay block and each mold

Answer 1

Answer:

One clay block = x = $2.50 from before.

One mold = y = $4.00

Step-by-step explanation:

Multiply the second one by -2 to get -12x-2y=-38.00

Add these equations to eliminate y:

-12x-2y=-38.00

3x+2y=15.50

Result: -9x+0y=-22.50

9x=22.50

x=$2.50
