Step-by-step explanation:
Let the price of each pounds of bananas be x andthe price of each pounds of grapes be y.
ATQ,
3x+4y = 10.25 ...(1)
2x+2y = 5.5 ..(2)
Multiply equation (2) by 2.
4x+4y = 11 ...(3)
Now, subtract equation (1) from (3).
4x+4y-(3x+4y) = 11-10.25
4x+4y-3x-4y = 0.75
x = 0.75
Put the value of x in equation (2)
2(0.75)+2y = 5.5
1.5+2y = 5.5
2y = 5.5 - 1.5
2y = 4
y = 2
So, there are 0.75 pounds of bananas and 2 pounds of grapes.
Answer:
1: 31.5. 2: 5. 3: 4.6 4: 45
<h3>For 5 toppings, cost of tony and bob are same</h3>
<em><u>Solution:</u></em>
Let "x" be the number of toppings
Given that,
Tony's hamburgers shack sells hamburgers for $2 plus $0.40 for each topping
Therefore,
Cost = 2 + 0.40x ----- eqn 1
Bob's burgers sells hamburgers for $3 dollars plus 20 cents for each topping
20 cents = $ 0.2
Therefore,
cost = 3 + 0.2x -------- eqn 2
For both the cost to be same, eqn 1 is equal to eqn 2
2 + 0.40x = 3 + 0.2x
0.40x - 0.2x = 3 - 2
0.2x = 1
Divide both sides by 0.2
x = 5
Thus, for 5 toppings, cost of tony and bob are same
It would be pounds, hope this helps :)
