Answer: the equation is 4t = 3.60
The cost of 1 pound of banana is $0.9
Step-by-step explanation:
Let t represent the cost of 1 pound of banana in dollars.
Gavin paid for 4 pounds of bananas. This means that the total cost of 4 pounds of banana will be 4× t = $4t
He gave a $10 bill to the seller and he was given back $6.40. This means that the actual cost of 4 pounds of banana would be
10 - 6.40 = $3.60
Therefore,
4t = 3.60
t = 3.60/4 = $0.9
900. If your formula is correct, you only have to multiply 300 by 3
Answer:
Step-by-step explanation:
we have
<em>The equation of the first line</em>
------> equation A
<em>The equation of the second line</em>
------> equation B
Solve the system of equations by elimination
Multiply equation A by -4 both sides
--------> equation C
Adds equation B and equation C
<em>Find the value of x</em>
substitute the value of y
Multiply by 3 both sides
therefore
The solution to the system of equations is the point

So if Isabella has 33 dollars that means they did 11x3=33 so to find Shanes you would do 3x3=9 then add the two together which is $42 hope this helps
3x + (5+35x) = 3x -30
38x + 5 = 3x -30
38x = 3x -35
35x = -35
x = -1
