You need to repair a broken fence in your yard. The hole in your fence is

around 3 meters in length and for whatever reason, the store you go to
has oddly specific width 20cm wood. Each plank of wood costs $16.20,
how much will it cost to repair your fence? (Hint: 1 meter = 100 cm) *

Answer:

cost = $ 243.00

Step-by-step explanation:

This exercise must assume that it uses a complete table for each piece, we can use a direct ratio of proportions, if 1 table is 0.20 m wide, how many tables will be 3.00 m

#_tables = 3 m (1 / 0.20 m)

#_tables = 15 tables

Let's use another direct ratio, or rule of three, for cost. If a board costs $ 16.20, how much do 15 boards cost?

Cost = 15 (16.20 / 1)

cost = $ 243.00
