Main Answer:
Let's denote the amount spent on buying new equipment as 
 and the amount spent on the maintenance of old equipment as
 and the amount spent on the maintenance of old equipment as 
 , where
, where 
 is a common multiplier.
 is a common multiplier.
Step-by-step explanation:
According to the given information, the ratio of the money spent on buying new equipment to the money spent on the maintenance of old equipment is 
 .
.
So, we have:
![\[ \frac{\text{Money spent on new equipment}}{\text{Money spent on maintenance}} = (4x)/(5x) \]](https://img.qammunity.org/2024/formulas/mathematics/high-school/2jrtosr4d6lyijwi10m8nxdkzmph14hfz6.png)
We know that the money spent on buying new equipment is $48,800.00. Therefore:
![\[ (4x)/(5x) = (48800)/(1) \]](https://img.qammunity.org/2024/formulas/mathematics/high-school/aucrd1h0dwu0ctg6et0i20gqb0pks7fgo2.png)
Now, cross-multiply to solve for 
 :
:
![\[ 4x * 1 = 5x * 48800 \]](https://img.qammunity.org/2024/formulas/mathematics/high-school/22bztluogavqokor7emyj6cvlwpilolgcr.png)
![\[ 4x = 244000 \]](https://img.qammunity.org/2024/formulas/mathematics/high-school/ws8msfc6wmsfsvlacze6e0iw0mpvhutnae.png)
Now, solve for 
 :
:
![\[ x = (244000)/(4) \]](https://img.qammunity.org/2024/formulas/mathematics/high-school/7geyxac0e42bxnb2v3sa1oqguxjl7im10i.png)
![\[ x = 61000 \]](https://img.qammunity.org/2024/formulas/mathematics/high-school/djtfgekckvneoasp8os8b3dq4ypujan3r3.png)
Now that we have the value of \(x\), we can find the amount spent on maintenance:
![\[ \text{Money spent on maintenance} = 5x \]](https://img.qammunity.org/2024/formulas/mathematics/high-school/i9g6lkgx16wfgn385oaqojfw2ldwleeetn.png)
![\[ \text{Money spent on maintenance} = 5 * 61000 \]](https://img.qammunity.org/2024/formulas/mathematics/high-school/g1jx5kii7cmccf6lrz1kvysn6isqs0nb54.png)
![\[ \text{Money spent on maintenance} = 305000 \]](https://img.qammunity.org/2024/formulas/mathematics/high-school/c695d9pye0qq59fzjeyu86stb0b86kl5vb.png)
Therefore, the amount spent on the maintenance of old equipment is $305,000.00.
