Answer:
y = (x/400)*14
Explanation:
y= how much money Anna earns
x= number the envelopes stuffed
(x/400) = how many $14 will get
y = (x/400)*14
Check or equation:
if Anna stuffs 400 envelopes then x= 400
the earns money y is y = (x/400)*14
y = (400/400)*14= 1*14 = $14 โ
if Anna stuffs 800 envelopes then x= 800
the earns money y is y = (x/400)*14
y = (800/400)*14= 2*14 = $28 โ
