You are participating in a school bake sale as a fundraiser for your basketball team. your goal is to raise at least $150 by selling brownies and cookies. you are selling brownies for $2.50 each and cookies for $1.50 each. first, select an inequality to represent the number of brownies, b, and cookies, c, you would need to sell to meet your goal of raising $150. then, select the possible number of brownies and cookies you could have sold to meet your goal.

2.5b + 1.5c ≥ 150

Example 100 brownies and 50 cookies

Step-by-step explanation:

To write an expression, define the variables.

c is number of cookies

b is number of brownies

To find the total money they earned, write 2.5b + 1.5c which includes the cost of each brownie and cookie.

2.5b + 1.5c ≥ 150 so you have at least $150.

This means you could sell 100 brownies and 50 cookies and earn $325.

i dont know

step-by-step explanation:

hello,

b) 62.47% of the students are between 14 and 18 years old.

step-by-step explanation:

mean = 15 and standard deviation = 2

student between 14 to 18

formula used z-score

for age 14 , z score

using z-table , p(z> -0.5)=0.3085

for age 18 , z score

using z-table , p(z< 1.5)=0.9332

p(-0.5< z< 1.5)=0.9332-0.3085 = 0.6247

thus, 62.47% of the students are between 14 and 18 years old.
