Question

Allison has 5 times as many baseballs cards as football cards.in all ,she 120 baseball and football cards.how many baseball cards does Allison have

Answer 1

well to help you solve this problem you should set an equation as so...

B=5F

B+F=120

Next you would plug in what B equals into the equation B+F=120 like so

5F+F=120

then you add like terms

6F=120

then you isolate the variable by dividing like so

6F=120$\frac{6F}{6} = \frac{120}{6}$

F=20

so Allison has 20 football cards and you would subtract 20 from 120

120-20=100

so Allison has 100 baseball cards
