Juan and Franco collect baseball cards. Juan has baseball cards. Franco has 18 fewer baseball cards than Juan. Together they hav

horsena [70]

Answer:

Franco has 66 baseball cards.

Step-by-step explanation:

This question can be solved by a system of equations.

I am going to say that:

x is the number of baseball cards that Franco has.

y is the number of baseball cards that Juan has.

Franco has 18 fewer baseball cards than Juan.

This means that:

$x = y - 18$

Also:

$y = x + 18$

Together they have 150 baseball cards.

This means that:

$x + y = 150$

Since $y = x + 18$

$x + x + 18 = 150$

$2x = 132$

$x = \frac{132}{2}$

$x = 66$

Franco has 66 baseball cards.
