Question

) Dan bought 5 new baseball trading cards to add to his collection. The next
day his dog ate half of his collection. There are now only 32 cards left.
How many cards did Dan start with ?

Answer 1

Answer:

Start by writing an equation with a a variable (call it X) to represent the number Dan started with.

 

He started with X, added 5 more, then his dog took half or divide by 2. He then ended up with 32. Solve:

 

(X +5)/2 = 32 Multiply each side by 2

X+5 = 64 Subtract 5 from both sides

X = 59

     

Answer 2

Answer:

59

Step-by-step explanation:

Let the Dan's baseball be x

When 5 added

(x + 5)

Dog ate half

(x + 5)/2

(x + 5)/2 = 32

(x + 5) = 32(2)

x + 5 = 64

x = 64 - 5

x = 59
