Diragio Lawn Care cuts 42 lawns every week. Each lawn uses 316 of a tank of gas when it is cut (on average).

Part A:
If the lawnmower had no gas at the start of the week, how many times would it have to be completely filled during the week? Show your work.

Part B:
The cost for a full tank of gas in the lawnmower is $20. How much does it cost (in lawnmower fuel only) to mow one average lawn? Show your work.

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

a_n = a_1 + (n - 1)d

the first term is 6.

the common difference d = ?

when you find d, replace n with 7 and d with the common difference to find your answer.
