Can Excel calculate two outputs from one number?

Question

I'm trying to calculate the J29 cell from Cost Model to output using the rates in Bps, where J29 in Cost Model should actually be $42,363.6 . This math comes from using [.0025 x (Bps D3 - Cost Model I25)] + [.002 x (J27-(Bps D3 - Cost Model I25))]

Is this feasible? Is there a formula that can calculate this?

Here are the formulas in Cost Model currently:

Cell J25: `=SUM(I25+J27)`
Cell J27: input by me
Cell J28: word-break: break-all;  

=IF(J25<='Bps Breakdown'!$D$3,'Bps Breakdown'!$F$3,IF('Cost Model'!J25<='Bps Breakdown'!$D$5,'Bps Breakdown'!$F$5,IF('Cost Model'!J25>'Bps Breakdown'!$D$6,'Bps Breakdown'!$F$6)))

Cell J29: `=(J27*J28)` 

Answer 1

I may have oversimplified this, but does this work?

=I28*('Bps Breakdown'!D3-'Cost Model'!I25)+
 J28*('Cost Model'!J27-('Bps Breakdown'!D3-'Cost Model'!I25))
