emily bought a wreath and 2 boxes of outdoor lights every year. the wreath costs $14.99 and each box of lights costs $3.99.
what is the total amount of money emily spent after 5 years?
a.
guess and test.
guess that emily spent $30. multiply $3.99 by 2. then add that answer to $14.99. divide this number by 5. if the answer is not 30, then revise your guess, and test your answer again.
b.
work backward.
start by multiplying $3.99 by 2 to find the cost of the lights. add the cost of the wreath to the sum and then divide by 5.
c.
draw a diagram.
draw a large circle. draw 2 squares inside the circle and a triangle. write $3.99 in each square and write $14.99 inside the triangle. add up all the amounts inside the circle ($22.97) to find the amount emily spent in 1 year. multiply the amount by 5 to find the amount spent in 5 years.
