The cost of purchasing a lawn mower and trimmer if the mower costs $12 more than twice the cost of the trimmer

2x + 12

Step-by-step explanation:

Let the cost of trimmer be x

As given that the cost of a lawn mower is $12 more than twice the cost of the trimmer.

Hence cost of the trimmer is x and twice the cost is 2x plus $12 more, so the expression will be

Cost of the mower = 2x + 12

Let cost of purchasing a trimmer be x

We know that cost of purchasing a lawn mower is $12 more than twice the cost of the trimmer

⇒ Cost of purchasing a lawn mower = 2*x + 12

Hence, cost of trimmer is x, and of the lawn mower is 2*x + 12
