Ihad been planning to work for 20 hours a week for 12 weeks this summer to earn $\$3000$ to buy a used car. unfortunately, i got sick for the first two weeks of the summer and didn't work any hours. how many hours a week will i have to work for the rest of the summer if i still want to buy the car?

24

Step-by-step explanation:

If the total amount that I earn for the summer is constant, then the number of hours I work each week and the total number of weeks that I work are inversely proportional. Consequently, if I only work 10/12=5/6 as many weeks, I need to work 6/5 as many hours each week. 6/5 times 20=24, so I need to work 24 hours a week.

(w – 2.5)(w + 2.5)

(–4v – 9)(–4v + 9)

step-by-step explanation:

add the numbers under frequency to find the total number:

5 + 8 +7 + 4 + 0 +1 = 25

the answer is 25.
