Q: Francis' family has 2 ukuleles, 4 guitars, and a certain number of violins. Each ukulele has 4 strings. Each guitar has 6 strings. Each violin has 4 strings. If the total number of strings among the ukuleles, guitars, and violins is 40 strings, how many violins does Francis' family have?
A: 2
Step-by-step reasoning process: From the ukuleles, there are 2 * 4 = 8 strings. From the guitars, there are 4 * 6 = 24 strings. From the violins, there are 40 - 8 - 24 = 8 strings. The total number of violins Francis' family has is 8 / 4 = 2 violins.


Q: For every white duck at the lake there are 5 fish. For every black duck there are 10 fish and for every multicolor duck there are 12 fish. Currently there are 3 white ducks, 7 black ducks and 6 multicolored ducks. How many fish are in the lake?
A: 157
Step-by-step reasoning process: For every white duck there are 5 fish and there are 3 white ducks for a total of 5 * 3 = 15 fish. For every black duck there are 10 fish and there are 7 black ducks for a total of 10 * 7 = 70 fish. For every multicolored duck there are 12 fish and there are 6 multicolored ducks for a total of 12 * 6 = 72 fish. All total there are 15 + 70 + 72 = 157 fish in the lake.


Q: Kenia has three times as many rats as Hunter and Elodie has together. If Elodie has 30 rats, 10 rats more than Hunter, calculate the total number of pets the three have together?
A: 200
Step-by-step reasoning process: Since Elodie has 30 rats, Hunter has 30 rats - 10 rats = 20 rats. Together, Elodie and Hunter have 20 rats + 30 rats = 50 rats. Kenia has three times as many rats as Hunter and Elodie have together, which is 3 * 50 rats = 150 rats. Together, the three have 150 rats + 50 rats = 200 rats.

Step-by-step reasoning process: After 5 days, Sara has baked 5 days * 10 cakes / day = 50 cakes. After Carol's feast, there are 50 cakes - 12 cakes = 38 cakes remaining. Sara needs 2 cans / cake * 38 cakes = 76 cans of frosting.
