The product of the ages (in days) of two newborn babies Simran and Jessie in two dayswill be 48 more than the product of their ages today. How old are the babies if Jessie is 2days older than Simran?

Respuesta :

Given that:

- The product of the ages (in days) of babies Simran and Jessie in two days

will be 48 more than the product of their ages today.

- Jessie is 2 days older than Simran.

Let be "j" Jessie's age (in days) and "s" Simran's age (in days).

You can set up the following System of Equations using the data given in the exercise:

[tex]\begin{cases}(j+2)(s+2)=js+{48} \\ j={s+2}\end{cases}[/tex]

You can use the Substitution Method to solve the system:

1. Substitute the second equation into the first one:

[tex](s+2+2)(s+2)=(s+2)s+48[/tex]

2. Solve for "s":

[tex](s+4)(s+2)=s^2+2s+48[/tex][tex](s)(s)+(s)(2)+(4)(s)+(4)(2)=s^2+2s+48[/tex][tex]s^2+2s+4s+8=s^2+2s+48[/tex][tex]\begin{gathered} 4s=48-8 \\ \\ s=\frac{40}{4} \\ \\ s=10 \end{gathered}[/tex]

3. Substitute "s" into the second original equation and evaluate:

[tex]\begin{gathered} j=10+2 \\ j=12 \end{gathered}[/tex]

Hence, the answer is: Jessie is 12 days old and Simran is 10 days old.
