Jason earns 30 cents for every carrot he sells. He earns an extra $3 for every 30 carrots he sells.How many carrots must he sell in order to earn $555?

3 answers

let the number of carrots sold be x

30x + 300x/30 = 55500
40x = 55500
x = 1387.5
assuming he cannot sell 1/2 a carrot
he must sell 1387 to make $555

check: 1387(.30) = $416.10
1387/30 = 46 7/30
(multiples of 30 in that region are 1320 , 1350, 1380, 1410 ..)
so he gets the bonus of 46(3) or $138
for a total of 554.1 , he is short 90 cents
which means 3 more carrots..

He must sell 1390 carrots.

Proof: 1390(.3) + 46(3) = 555
OK so basically he earns 30 cents for each carrot

multiply 30 by .3 to get $9 for 30 carrots
Then add $3 to this amount to get $12 dollars.
Divide 555 by 12 to get 46 R3.
Multiply 46 by 30 because its 46 bundles of 30 carrots
Then divide the 3 dollars by .3 for each carrot to get 10 carrots

1380+10 = 1390
Use JOHN CENA’S reply. I had this question before and the teacher told us to use that strategy - it works!
