Step-by-step explanation

Mackenzie has 1 dollar, 2 dimes, and 3 pennies.

Recall


\begin{gathered} 1\text{ dime =0.1 dollar} \\ 1\text{ penny =0.01 dollar} \end{gathered}

Therefore, the total sum that Mackenzie has becomes;


1+2(0.1)+3(0.01)=1+0.2+0.03=1.23

Let d represent dimes and p represent pennies. Therefore, the total dimes and pennies Jorge could have becomes


0.1d+0.01p

Since both individuals have the same amount of money


0.1d+0.01p=1.23

Hence the equation is model as;

ANSWER:


0.1d+0.01p=1.23
