Answer 1

The minimum number of times Jenny needs to mows the lawn be 4 .

Explanation:

Let us assume that the number of times Jenny needs to mows the lawn be x .

As given

Jenny has $25 and she earns $10 for each lawn that she mows.

Jenny wants to buy a concert ticket that costs $65.

Than the equation becomes

25 + 10x = 65

10x = 65 - 25

10x = 40

`x = (40)/(10)`

x = 4

Therefore the minimum number of times Jenny needs to mows the lawn be 4 .
