Answer:

They have 48 cards.

Step-by-step explanation:

let s be the number of Shauntay's cards and j be the number of Jessica's cards.

The ratio of Shauntay's cards to Jessica's cards is 5 to 3, then

(1) \frac{s}{j} =\frac{5}{3}

After Shauntay gives Jessica 12 of her cards, both girls have the same number of cards, then

(2) s-12 =j+12.

From (2), we get s= j+24. If we put j+24 instead of s in (1) we get:

\frac{j+24}{j} =\frac{5}{3}

3×j+24×3 = 5×j  From this we get;

2×j=72  and j=36

After Shauntay gives Jessica 12 of her cards, Shauntay and Jessica would have 48 cards.
