The total cost for the entire life span of the deep fryer  is computed below:
Brand P total cost =Purchase price + total electricity cost 
                                = $144+($0.49x8x12x6)
                                =$426.24
Brand Q total cost =(Purchase price x 3)+ total electricity cost
                                =( $37.5x3)+($0.75x 8x12x6)
                                =   $544.5
Difference = Brand Q-Brand P
                   =$544.5-$426.24
                   =$118.26
Robert will have to choose Brand P because it will be cheaper by $118.26 than Brand Q in their entire lifetime.

While representing 3 - 4 on the number line, from the starting point 0, we need to show an arrow to three numbers on the right.

Since - 4 is the additive inverse of 4, from the point where the first arrow pointed, we should go 4 points to the left.

Hence, the number line which shows an arrow from 0 to 3, and then from 3 to negative 1 is the correct one.

Step-by-step explanation:

Hope that helps!!

There was no more rainfall for the rest of the day.

There’s no exact value listed on this graph, but it would be where the line ends completely on the far right. The rain was fluctuating throughout the day when the graph was going up and down. when the graph completely stops, the rain did too.
