Steve is building a bench for the playground and needs 6 lengths of wood that measure 4 feet and 2 lengths of wood that measure 2 feet. How many feet of wood does Steve need to buy? Give the rationale and then the answer.
Let's think step by step. Steve needs 6 lengths of 4 feet of wood or 6 x 4 = 24 feet of wood. He also needs 2 lengths of 2 feet of wood or 2 x 2 = 4 feet of wood. Altogether, Steve needs 24 feet of wood + 4 feet of wood = 28 feet of wood.. The answer is: 28.

Mica went to the grocery store and bought 2 kilograms of pasta that costs $1.5; 1/4 kilogram of ground beef costs $8 for 1 kilogram; two jars of pasta sauce costs $2 per jar. Mica also wants to buy a $6 Quesadilla for snacks. How much money should she have with her to buy all those? Give the rationale and then the answer.
Let's think step by step. Two kilograms of pasta cost $1.5 x 2 = $3. One - fourth kilogram of ground beef cost $8 x 1 / 4 = $2. Two jars of pasta sauce cost $2 x 2 = $4. The total cost for the pasta, beef, and sauce is $3 + $2 + $4 = $9. Since Mica also wants to buy Quesadilla, she should have $9 + $6 = $15.. The answer is: 15.
