Answer this question: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?
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.

Answer this question:Kendra tracks the different species of birds they spot on their birdwatching trip. On Monday they visited 5 sites and saw an average of 7 birds at each site. On Tuesday, Kendra visited 5 sites and saw an average of 5 birds at each site. On Wednesday visited 10 sites and saw an average of 8 birds at each site. On average, how many different birds did Kendra see on each site?
On Monday Kendra saw 5 sites x 7 birds / site = 35 different birds. On Tuesday Kendra saw 5 sites x 5 birds / site = 25 different birds. On Wednesday Kendra saw 10 sites x 8 birds / site = 80 different birds. In total Kendra saw 35 birds + 25 birds + 80 birds = 140 different birds. In total Kendra visited 5 sites + 5 sites + 10 sites = 20 sites. On average Kendra saw 140 birds / 20 sites = 7 different birds at each site.

Answer this question:There are 100 students in class and the ratio of boys to girls is 3:2. How many more boys than girls are there?
The class was divided into 3 + 2 = 5 parts. So each part is equal to 100 / 5 = 20 students. Since there are 3 parts for boys, then there are 20 x 3 = 60 boys in class. So there are 100 - 60 = 40 girls in class. Hence, there are 60 - 40 = 20 boys more than girls.
The answer is 20.

Answer this question:Jack needs to mop the bathroom and the kitchen. If the bathroom floor is 24 square feet and the kitchen floor is 80 square feet, and Jack can mop 8 square feet per minute, how many minutes does he spend mopping?
First find the total floor area Jack needs to mop: 24 sq ft + 80 sq ft = 104 sq ft. Then divide the total area that needs to be mopped by Jack's mopping rate: 104 sq ft / 8 sq ft / minute = 13 minutes.
