Answer: The expression shows the number of dollars he will have saved by the end of the year is given by [tex]35(7)+40(5)=\$445[/tex]
Step-by-step explanation:
Since we have given that
Amount he saved per month over the first 7 months = $35
Amount he saved per month over the next 5 months = $40
So, total saving by the end of the year is given by
[tex]35\times 7+40\times 5\\\\=\$245+\$200\\\\=\$445[/tex]
Hence, the expression shows the number of dollars he will have saved by the end of the year is given by
[tex]35(7)+40(5)=\$445[/tex]
