- 5. Multiple ChoiceThe 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?1s + 3c = 38
2s + 3c = 523s + 1c = 38
3s + 2c = 52s + c = 38
s + c = 523s + 3c = 38
1s + 2c = 52 - 6. Multiple ChoiceDennis 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 = 6.60
.10d + .05n = 80d + n = 80
d + n = 6.60d + n = 80
.10d + .05n = 6.60d + n = 80
.05d + .10n = 6.60 - 7. Multiple Choice(3x4)(4x2)7x612x67x812x8
