Answer :
Answer:
He needs to sell at least 7 birdhouses.
Step-by-step explanation:
Jack earns $229 every week and wants to earn $320. Since he is guaranteed to make $229 already, you can subtract that from $320 resulting in $91 he needs to make up.
Each birdhouse sells for $14. He needs to sell enough to make $91.
You can solve this by repeated addition or division.
14 + 14 + 14 + 14 + 14 + 14 + 7 = 91.
Or.
91/14 = 6.5
However, you cannot end up with half of a birdhouse. So, you need to sell at least 7 birdhouses so you can get at least $91.
Hope this helps.
Answer:
Step-by-step explanation:
This question can be turned into a simple algebraic equation. Since he earns $229 a week, we add that to how many birdhouses he sells. Since we're finding out how many he needs to sell, we'll put a letter next to the $14 he gets for each birdhouse. Lastly, he wants to earn $320 this week, so that will be on the other side of the equal sign.
You should come up with this equation:
229 + 14x = 320
Firstly, we subtract 229 from 320, since they're on opposite sides of the equal sign.
14x + 320-229
14x = 91
Next, we divide 91 by 14.
x = 91/14
x = 6.5
So, Jack needs to sell 6.5 birdhouses in order to get $320. Or, since he wants at least $320, he could sell 7.
