- Q1The school that Stefan goes to is selling tickets to a choral performance. On the first day of ticket sales the school sold 3 senior citizen tickets and 1 child ticket for a total of $38. The school took in $52 on the second day by selling 3 senior citizen tickets and 2 child tickets. Which equations represents the system that could be used?3s + 1c = 38 3s + 2c = 523s + 3c = 38 1s + 2c = 521s + 3c = 38 2s + 3c = 5230sM8AL-Ij-2
- Q2Last season two running backs on the Steelers football team rushed a combined total of 1550 yards. One rushed 4 times as many yards as the other. Let x and y represent the number of yards each individual player rushed. Which system of equations could be used?y - x = 1550 y = 4xy = 1550 + x y = x + 4x + y = 1550 y = 4xx + y = 1550 y = x + 430sM8AL-Ij-2
- Q3Dennis mowed his next door neighbor’s lawn for a handful of dimes and nickels, 80 coins in all. Upon completing the job he counted out the coins and it came to $6.60. Which system of equations could be used to find the exact number of dimes and nickels?d + n = 80 .10d + .05n = 6.60d + n = 80 .05d + .10n = 6.60d + n = 80 d + n = 6.60d + n = 6.60 .10d + .05n = 8030sM8AL-Ij-2
- Q4On Monday Joe bought 10 cups of coffee and 5 doughnuts for his office at the cost of $16.50. It turns out that the doughnuts were more popular than the coffee. On Tuesday he bought 5 cups of coffee and 10 doughnuts for a total of $14.25. Which equations could be used to determine the cost of the coffee?10c + 5d = 14.25 5c + 10d = 16.50c + d = 5 5c + 10d = 16.50c + d = 10 5c + 10d = 16.5010c + 5d = 16.50 5c + 10d = 14.2530sM8AL-Ij-2
- Q5A large pizza at Palanzio’s Pizzeria costs $6.80 plus $0.90 for each topping. The cost of a large cheese pizza at Guido’s Pizza is $7.30 plus $0.65 for each topping. Which system of equations could be used to find the number of toppings when both companies cost the same amount?y = 6.80+.90x y = 7.30 + .65xy + .90x = 6.80 y + .65x = 7.30x + y = 6.80 x + y = 7.30y = 6.80 + .65x y=7.30+.90x30sM8AL-Ij-2
