In what group of 120 seventh graders, 30% have completed their science project. how many students have completed their science project?​

36

Step-by-step explanation:

30% of 120 is 120 x 0.3

120 x 0.3 =36.

d) 48

step-by-step explanation:

16,32,48,64,80,96,112,128,144,160,176,192,208,224,240,256,272,288,304,320,336

(2,20) means that the 2 is 2 hours and 20 is 20$. so there both 20$ for 2 hours only the same price. like it says. so, the dunk tank and the bounce house are the same price (20$) for the same amount of time (2 hours).
