Question

Anderson earns $20 per month for completing chores around the house. Each month, the amount Anderson earns increases by $0.50. Which expression represents how much total money Anderson earns from month 3 to month 18?

Answer 1

Mathematical equation -

20 + 0.50x = ?

X is the placeholder which in this case equals months

But in this case you want to look for form month three to month 18 (which is 15 months) so three months went by so the equation is

$61.50(being the three months already)

(20+(0.50*15))+61.50=?
