Twelve of the 20 students in Mr. Skinner’s class brought lunch from home. Fourteen of the 21 students in Ms. Cho’s class brought

babymother [125]

Solution:

Number of students in Mr.Skinner's class who brought lunch from home if there are 20 students in the class=12

Fraction of students who brought lunch from home in Mr. Skinner's class= $\frac{12}{20}=\frac{3}{5}$

Number of students in Ms. Cho's class who brought lunch from home if there are 21 students in the class=14

Fraction of students who brought lunch from home in Ms. Cho's class= $\frac{14}{21}=\frac{2}{3}$

As Siloni is using two 15-section spinners to simulate randomly selecting students from each class and predicting whether they brought lunch from home or will buy lunch in the cafeteria.

Number of Congruent sectors in each Spinner=15

So, if we represent students from Mr. Skinner's class who brought lunch from home in Spinner having 15 congruent Sectors = $\frac{9}{15}$

So, if we represent students from Mrs. Cho's class who brought lunch from home in Spinner having 15 congruent Sectors = $\frac{10}{15}$

Mr Skinner class +1 = Mr's Cho's Class

So Ms Cho's class =One more sector of the Skinner-class spinner will represent bringing lunch from home.

Option A which is One more sector of the Skinner-class spinner will represent bringing lunch from home represents Ms Cho's Class.

Jeo is comparing the price of different boxes of cereal. One box has 16 oz. and costs $3.50. Another costs $3.89 for a 24 oz. bo

velikii [3]

Answer:

The difference in cost, in dollars, per ounce between the two boxes of cereal is $0.06.

Step-by-step explanation:

☆Let's solve using proportion.

☆One box:

$\frac{16 \: oz.}{3.50 \: dollars} = \frac{1 \: oz.}{x} \\ \\ \frac{3.50}{16} = \frac{16x}{16 } \\ \\ 0.22 = x$

☆Another box:

$\frac{24 \: oz.}{3.89 \: dollars} = \frac{1 \: oz.}{x } \\ \\ \frac{3.89}{24} = \frac{24x}{24} \\ \\ x = 0.16$

☆All we need to do is subtract: $0.22 - 0.16 = 0.06$

☆The difference in cost, in dollars, per ounce between the two boxes of cereal is $0.06.
