Step-by-step explanation:
7*3y - 7*5 + 2*4y + 12
= 21y - 35 + 8y + 6
= 29y - 29
= 29(y-1)
the name of the horizontal axis is A. x-axis
Uhuh, uhuh, and then what happened?
The storekeeper bought it for $25. The reason he has the store is to make some money so he can feed his family. The way he does that is to sell things for a little more than he paid for them. The amount he adds on top of his cost is called his "markup".
For this item, he paid $25 to put it in his store, and he decided to sell it for $35.
He marked it up by $10 out of $25.
10 / 25 = 40% .
