denis-greek [22]

Answer:$570

Step-by-step explanation:If it is 900 for 2 walls, and they need 6 walls, then multiply 900 by 3. They would use 2700 bricks for 6 walls. Multiply 2700 by 0.10 to get the price for all the bricks, 270 dollars. If labor to build each wall costs 50 dollars then multiply that by 6 and add it to the 270 dollars. It costs 570 dollars to build 6 walls

Customers of a phone company can choose between two service plans for long distance calls. The first plan has a $22 monthly fee
vladimir2022 [97]
Company a = 22 + 0.07m
company b = 8 + 0.12m

We are looking for the time when the prices are equal. i.e. the price of company a = the price of company b

company a = company b
22 + 0.07m = 8 + 0.12m
22 - 8 = 0.12m - 0.07m
14 = 0.05m
m = 14/0.05
m = 280

Therefore, the two companies will cost the same if you talk for 280 minutes
