Question

bob bought 3 packs of model xars.he gave 4 cars to ann.bob has 11 cars left.how many model cars were in each pack

Answer 1

Well since he gave Ann 4 cars and 11 are left, you would add them up which gives u a total of 15 cars. Now you would have to divide 15 by 3 (the total number of pack) which is 5. This means that there were 5 cars in each pack

Answer 2

There are 5 model cars were in each pack.

Let x represent the number of each cars in each model.

Since bob bought 3 packs of model cars, hence:

Number of cars Bob bought = 3x

He gave out 4 cars to Ann and still had 11 cars left, hence:

3x - 4 = 11

3x = 15

x = 5 cars

Hence there are 5 model cars were in each pack.
