Question: In a grocery store, the daily salary of the manager is $5 and the clerk is $2. If there are currently 2 managers and 3 clerks employed in the grocery store, how much is the total daily salary of all the employees of the grocery store?
Answer with step-by-step thinking: The 2 managers earn $5 x 2 = $10 per day. The daily salary of 3 clerks is $2 x 3 = $6. Therefore the total salary of all employees of the grocery store is $10 + $6 = $16.
So the answer is 16.


Question: Julia had to make 6 cakes for the party. Each cake takes 12 minutes to mix and needs 9 more minutes to bake than mix. Then it takes 6 more minutes to cool and decorate than to bake. How many hours will it take to make all 6 cakes?
Answer with step-by-step thinking: It takes 12 + 9 = 21 minutes to bake each cake. It takes 21 + 6 = 27 minutes to cool and decorate each cake. Therefore, it takes a total of 12 + 21 + 27 = 60 minutes to make one cake. Thus, it takes 60 / 60 = 1 hour to bake one cake. So, it will take 1 x 6 = 6 hours to bake all 6 cakes.
So the answer is 6.


Question: The dinner bill for 6 friends came to $150. Silas said he would pay for half of the bill and the remaining friends could split the rest of the bill and leave a 10% tip for the whole meal. How many dollars will one of the friends pay?
Answer with step-by-step thinking:
Silas paid half = 150 / 2 = 75. Remaining bill paid by 5 friends = 75 + 10% of 150 = 75 + 15 = 90. Each person will pay 1 / 5 which is 90 / 5 = 18. Each friend will pay $18.
So the answer is 18.
