D. Yes, Jason was $13 over his goal

Answer 1

`A.)\ No,\ Jason\ was\ \$20\ under\ his\ goal`

Explanation:

`Per\ day\ earning\ of\ Jason=2.5n+75\ \ \ \ \ \ \ \ where\ n\ is\ number\ of\ subscriptions\ Jason\ sells\\\\On\ a\ particular\ day\ Jason\ sold\ 42\ subscriptions\\\\\Rightarrow n=42\\\\Earning\ on\ that\ particular\ day=2.5* 42+75\\\\Earning\ on\ that\ particular\ day=105+75\\\\Earning\ on\ that\ particular\ day=\$180\\\\180<200\\\\Amount\ he\ has\ less\ than\ the\ required=200-180=\$20\\\\So\ Jason\ got\ \$20\ less\ than\ his\ goal.`
`Correct\ option\ is\ A.\ No,\ Jason\ was\ \$20\ under\ his\ goal`
