Your school drama club is putting on a play and hopes to raise $600 from ticket sales. they sell adult tickets for $8 each and student tickets for $5 each. let x represent the number of adult tickets and y represent the number of student tickets. the equation to represent the number of tickets sold to reach their goal, 8x+ 5y = 600, is graphed below. if 40 student tickets are sold, how many adult tickets must be sold to reach their goal?

(type an integer or a decimal.) b. the average power use is nothing _ watts. (round to the nearest whole number as needed.) c. to generate the electricity you used, nothing _ l is needed. (round to the nearest whole number as needed.) to generate the electricity you used, nothing _ gal is needed. (round to two decimal places as needed.)
