Answer :
We can begin by defining Penny's total wealth as a mix of a set sum and a portion of Susie's wealth to develop an expression of how much money she has. We are informed that Penny has at least $4.50 and an additional 2/5 of Susie's wealth. Hence, we can write:
p = $4.50 + (2/5)s
where p is Penny's wealth, s is Susie's wealth, and s is represented by the letters.
If Susie has $11.50, we may enter s = $11.50 into the formula for p to see how much Penny has:
p = $4.50 + (2/5)($11.50)
p = $4.50 + $4.60
p = $9.10
As a result, Penny has $9.10 and Susie has $11.50.
In conclusion, the equation for Penny's wealth in terms of Susie's wealth is p = $4.50 + (2/5)s. When we enter s = $11.50 into the formula, we obtain p = $9.10, which is how much money Penny has while Susie has $11.50.
