Each trip, a bus drops off more fans at a concert. on the first trip, the bus dropped off 30. on the 14th trip, which was the last one, the bus dropped off 95 fans. how many fans did the bus deliver to the concert in total

There are 875 fans the bus deliver to the concert in total.

Step-by-step explanation:

Since we have given that

On the first trip, the bus dropped off = 30

Here a = first term = 30

On the 14 trip, the last trip, the bus dropped off = 95

i.e.

So, the total number of fans the bus deliver to the concert is given by

Hence, there are 875 fans the bus deliver to the concert in total.

you never say the total so we cant find the percentage used for petrol

step-by-step explanation:

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40
