Respuesta :
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
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.
