giovani is making a path in his backyard out of stone. he is trying to decide between granite and marble. granite costs $3 per stone. marble costs $5 per stone. giovanni would need 9 granite stones to make his path, or he would need 6 marble stones. which type of stone is more cost - effective for the garden path? the path would be cheaper if giovanni used stones.
Answer
Explanation:
Step1: Calculate cost of granite
Cost of granite = Number of granite stones * Cost per granite stone. Given 9 granite stones and cost per stone is $3, so Cost of granite = 9*3 = 27$.
Step2: Calculate cost of marble
Cost of marble = Number of marble stones * Cost per marble stone. Given 6 marble stones and cost per stone is $5, so Cost of marble = 6*5 = 30$.
Step3: Compare costs
Since 27 < 30, granite is more cost - effective.
Answer:
Granite
