Answer:
this is how!!!
Explanation:
so since it says “unit price” (also says dollar per bananas) all you have to do is make a variable and substitue
So:
Let number of bananas be “ b “
0.50b
0.5(4)
2
2 dollars
It the same for the rest except the last two
Since you dont know the number of bananas, let b be unknown, but may it equal to the cost given. For example:
10 = 0.5b
Since you dont know b
To solve for b, you have to make b be all by itself (like me when my cousin is sleeping on the other side of the world ;’) )
To do that you have to divide 0.5 to both sides
10 / 0.5 = 0.5b / 0.5
This will remove 0.5 from the right side and isolate b
Since b and 0.5 are being multiplied you can factor 0.5 out from the right side
10 / 0.5 = b
Now simplify
B = 20 bananas
