5. Use the equation shown to answer a-b.
soldi70 [24.7K]

Answer:

a. No

b. 2.25 days

Step-by-step explanation:

0.75x + 3 = 0.25x + 5.25

a......................

Constants are $3 and $5.25 respectively

Topping costs $0.75 and $0.25 respectively

To have same cost the toppings number would be different as cost is different.

Suppose the number of toppings is x in one shop and y in the other, then the spending if same, we get this equation:

  • 0.75x + 3 = 0.25y + 5.25

The answer is NO due to two different variables in the equation

b.......................

Constants are $3 and $5.25 respectively

Joseph adds $0.75 each day and Kelsey spends $0.25 each day

Number of days should be same in this case, so variable will be same and the result (amount left in bank) is same.

<u>So the equation for this case is:</u>

  • 3 + 0.75x = 5.25 - 025x

<u>Solving, we get:</u>

  • 0.75x + 0.25x = 5.25 - 3
  • x = 2.25

This is the solution to equation despite being a whole number.
