Dan pays £714.73 a year on his car insurance
LenaWriter [7]

Answer:

The Current Insurance cost = $685.43

Step-by-step explanation:

Given that Dan pays £714.73 a year on his car insurance.

Reduced Percentage = 4.1%

so

Reduced Amount =  4.1% × 714.73

                             = [4.1 / 100] × [714.73]

                             = 0.041 × 714.73

                             = $29.30

The current cost can be calculated by subtracting the reduced amount of 29.30 from 714.73.

so

Current Insurance cost = 714.73 - 29.30

                                       = $685.43

Therefore, the Current Insurance cost = $685.43

A local restaurant allows groups to rent out a party room in order to host events. The restaurant charges $600 to rent the room
OleMash [197]

Answer:

y = (10x + 600)/x

Step-by-step explanation:

To find the average cost, we must divide the total cost by the number of people.

The number of meals served will equal the number of people, since everybody gets just 1 meal.

Each meal is 10 dollars, plus the 600 rental fee.

The total cost will be the meal prices plus the fee, all divided by the number of people/number of meals, or x.
