An artist uses 3 ounces of paint for every large canvas they cover, and 2 ounces of paint for every small canvas they cover. They have completed 3 large paintings and 4 small paintings. How many ounces of paint have they used?
Let's think: The large paintings have used 3 * 3 = 9 ounces. The small paintings have used 2 * 4 = 8 ounces. In total, all the paintings haveused 9 + 8 = 17 ounces.. The answer is: 17.

A soccer team has three goalies and ten defenders. The team also has twice as many midfielders as defenders, and the rest of the players are strikers. If the team has 40 players, how many strikers are in the team?
Let's think: The team's total number of goalies and defenders is 3 + 10 = 13. The number of midfielders in the team is twice the number of defenders, which means there are 2 * 10 = 20 defenders in the team. The total number of players in the team playing the positions of goalies, defenders and midfielders is 20 + 13 = 33. If there are 40 players in the team, then the number of strikes in the team is 40 - 33 = 7.. The answer is: 7.

A pharmacy is buying enough tubs for them to make their prescriptions this week. They already have 20 tubs left in storage but they need a total of 100 tubs for the week. Of the tubs they still need to buy, they buy a quarter from a new vendor then decide to go to their usual vendor for the rest. How many tubs is the pharmacy going to buy from the usual vendor?
Let's think: They already have 20 tubs in storage, so they only need to buy 100 needed tubs - 20 tubs in storage = 80 tubs. From the new vendor, they buy 80 tubs / 4 = 20 tubs. They now have a total of 20 + 20 = 40 tubs. They are therefore going to buy 100 needed tubs - 40 owned tubs = 60 tubs from the usual vendor.. The answer is: 60.

Nina wants to give presents to her children. She buys three toys at $10 each, two packs of basketball cards at $5 each, and five shirts at $6 each. How much does she spend in all?
Let's think:
Three toys cost 3 x $10 = $30. Two packs of basketball cards cost 2 x $5 = $10. And, five shirts cost 5 x $6 = $30. Therefore, Nina spends a total of $30 + $10 + $30 = $70 in all.. The answer is: 70.
