sasho [114]

Answer:

1. n + 4

2. x(n) + 4

Step-by-step explanation:

The two solutions were arrived at based on the following :

1. The total number of fruit, irrespective of the kind or type.

In this case, let the number of fruit be n.

Adding 4 peaches gives: n + 4 fruits.

2. The second expression takes into account the peaches only.

This times around, let the total fruits be n.

The number of peaches in the basket can be given as a fraction. Let the fraction be <em>x</em>

The number of peaches is the fraction of peaches multiplied by the total number of fruit like this: <em>x</em>n

However, 4 peaches are added, therefore, the total number will be <em>x</em>n+4

This figure denotes the number of peaches in the basket.
