The cost of a slice of cake is three-fourths of the cost of a cup of milk tea. If the milk tea costs $2.40, how much do 2 slices of cake and 1 cup of milk tea cost?
Let's think: The cost of a slice of cake is $2.40 x 3 / 4 = $1.80. So, 2 slices of cake cost $1.80 x 2 = $3.60. Therefore, 2 slices of cake and 1 cup of milk tea cost $3.60 + $2.40 = $6.. The answer is: 6.

A group of hawks is called a kettle. It is breeding season for hawks. A group of ornithologists are tracking 6 kettles of hawks. Each kettle has an average of 15 pregnancies that yield 4 babies per batch. How many babies are expected this season if approximately 25% are lost?
Let's think: Each kettle has 15 hawks that get pregnant and each one yields 4 babies per pregnancy so there are 15 * 4 = 60 babies expected per kettle. If 60 baby hawks are expected per kettle and the ornithologists are tracking 6 kettles total then there are 60 * 6 = 360 baby hawks expected across all six kettles this breeding season. If there 25% of eggs do not hatch, then we are looking for 25 (percent that do not make it) / 100 (total number of babies expected) = .25 (percentage converted to decimal form for the proportion of expected baby hawks to be lost). The total number of baby hawks expected equals 360 * .25 expected los s = 90 babies not expected to hatch (lost). There are 360 total number of baby hawks expected and there are 90 babies expected to be lost so 360 - 90 = 270 remaining baby hawks expected this breeding season.. The answer is: 270.

Isabella and Alexis went to the mall to buy some pants and dresses. Alexis bought 3 times more pants and dresses than Isabella. If Alexis bought 21 pairs of pants and 18 dresses, how many pairs of pants and dresses did Isabella buy in total?
Let's think: The number of pants Isabella bought is 21 / 3 = 7 pairs of pants. The number of dresses Isabella bought is 18 / 3 = 6 dresses. The total number of pants and dresses Isabella bought is 7 + 6 = 13.. The answer is: 13.

Chad is hosting a BBQ on the hottest day of the year, where there will be a total of 15 people. He will need 2 pounds of ice per person to account for the heat. One pound bags of ice are sold for $3.00 for a pack of 10. How much will he spend on ice?
Let's think:
He's inviting 15 guests and will need 2 pounds per person so he will need 15 * 2 = 30 pounds of ice. Ice is sold in 10 - pound bags and he needs 30 pounds so he will need 30 / 10 = 3 bags of ice. Each bag is $3.00 and he needs 3 bags so they will cost 3 * 3 = $9.00.. The answer is: 9.
