An electronics store advertised tablets (t) for $349 and phones (p) for $469. During one month, they sold a total of 44 devices for a total of $17,516. Which system of equations could be used to calculate the cost of a tablet and the cost of a phone? No work is needed.
(1 Point)
349t + 469p = 44 and t + p = 17516
t + p = 44 and 349t + 469p = 17516
349t = 17516 and 469p = 17516
t + p = 44 and t + p = 17516

3.Ted has $6.80 in quarters and dimes. He has a total of 38 coins. Which equations can be used to calculate q, the number of quarters, and d, the number of dimes? No work is needed.
(1 Point)
.25q + .10d = 38 and q + d = 6.80
q + d = 38 and .25q + .10d = 6.80
.25q = .10d and q + d = 6.80
.25q + .10d = 38 and .25q + .10d = 6.80

5.Mr. Newman bought 8 tickets to a chili supper and spent a total of $30. He bought a combination of adult tickets for $5 each and child tickets for $3 each. Which system of equations will determine the number of child tickets, c, and the number of adult tickets, a, he bought? No work is needed.
(1 Point)
5a + 3c = 8 and a + c = 30
8a + 5c = 30 and a + c = 3
a + c = 8 and 3a + 5c = 30
5a + 3c = 30 and a + c = 8
6.Sarah and James are selling popcorn and cotton candy at the State Fair. Sarah sold 3 bags of popcorn and 9 bags of cotton candy for a total of $75.

7.Alley bought 7 bags of gummy bears and 3 bags of chocolate for $22. Ben bought 6 bags of gummy bears and 2 bags of chocolate for $16. Which system of equations could you use to calculate the cost of a bag of gummy bears (g) and a bag of chocolate (c)? No work is needed.
(1 Point)
7g + 3c = 16 and 6g + 2c = 22
7g + 3c = 22 and 6g + 2c = 16
7g + 6c = 22 and 3g + 2c = 16
g + c = 22 and g + c = 16
