Which strategies can be used to solve this problem?
the candle factory made 1,200 candles per month in june and july and 1,345 candles per month in august and september. what is the total number of candles they made in four months?
choose all answers that are correct.

a. use logical reasoning.
multiply 1,200 by 2 to figure out how many candles were made in june and july. multiply 1,345 by 2 to figure out how many candles were made in august and september. add the two numbers together to find the total number of candles made in four months.
b. draw a diagram.
draw two circles. in one circle write 1,200 and in the other circle write 1,345. add the numbers in the circles together.
c. work backward.
divide 1,200 by 2 (for the 2 months, june and july). then divide 1,345 by 2 (for the 2 months august and september). add these two numbers.
d. translate into an equation.
1,200 × 2 + 1,345 × 2 = c
