I am going to guess that the family's annual heating bill is $\$1,000.00.$ If they save 8% per year how much would they save in a year? How much in two years? Write this result as a number sentence. Now suppose the annual heating bill is $\$X.$ Write the number sentence above with the annual heating bill as $\$X$ rather than $\$1,000.00.$ Solve for $X.$ Write back if you need more assistance,
