Your school’s band decides to sell cookie dough kits to raise money for a spring field trip. There is a Family Times Cookie Doug

nikitadnepr [17]

Answer:

Step-by-step explanation:

let the Cookie Dough kit be x

and Baker’s Delight kit be y

cost of Cookie Dough kit= $7

cost of Baker’s Delight= $15

x+y=220------------1

7x+15y=2100------2

solve for x and y we have

multiply eqn 1 by 7 and subtract

7x+7y=1540---------3

- 7x+15y=2100-------2

0x-8y=-560

8y=560

divide both sides by 8 we have

y=560/8

y=70

put y=70 in eqn 1 we have

x+70=220

x=220-70

x=150

x=220-70

x=150

A. How many of each type of kit should your band purchase to raise the most money

Cookie Dough kit= 150

Baker’s Delight= 70

B. What is the most money that your band can raise?

Cookie Dough kit profit= selling price-cost price= 12-7= $5

Baker’s Delight profit= selling price-cost price= 25-15= $10

Amount made for Cookie Dough = 150*5=$750

Amount made for Baker’s Delight = 70*10=$700

total= 750+700= $1450

Sonia has 5 yellow hair clips, 2 red hair clips and 3 blue hair clips. What is the probability she was picks a yellow hair clip

Hatshy [7]

Answer:

The probability that Sonia picks a yellow hair clip and a blue hair clip without replacement = $\frac{1}{6}$

Step-by-step explanation:

Given:

Sonia has:

5 yellow hair clips

2 red hair clips

3 blue hair clips

To find the probability that she picks a yellow hair clip and a blue hair clip without replacement.

Solution:

Total number of clips = $5+2+3$ = 10

The probability that Sonia picks a yellow clip from the lot will be :

⇒ $\frac{\textrm{Number of yellow clips}}{\textrm{Total number of clips}}$

⇒ $\frac{5}{10}$

Simplifying fraction by dividing both numbers by their G.C.F.

⇒ $\frac{5\div 5}{10\div 5}$

⇒ $\frac{1}{2}$

Since no replacement is taking place, so after picking a yellow clip from the lot, the number of clips is decreased by 1.

So, new number of clips = $10-1$ = 9

The probability that Sonia picks a blue clip from the remaining lot will be :

⇒ $\frac{\textrm{Number of blue clips}}{\textrm{Total number of clips}}$

⇒ $\frac{3}{9}$

Simplifying fraction by dividing both numbers by their G.C.F.

⇒ $\frac{3\div 3}{9\div 3}$

⇒ $\frac{1}{3}$

The probability that she picks a yellow hair clip and a blue hair clip without replacement can be given as:

⇒ $\frac{1}{2}\times \frac{1}{3}$

⇒ $\frac{1\times 1}{2\times 3}$

⇒ $\frac{1}{6}$ (Answer)

General Formulas and Concepts:

Pre-Algebra

Equality Properties

Geometry

Vertical Angles

Step-by-step explanation:

Step 1: Set up equation

3x = x + 26

Step 2: Solve for x

Subtract x on both sides: 2x = 26
Divide 2 on both sides: x = 13
