Answer:
$13.60
Step-by-step explanation:
First let's find how much Gerry spends on lunch in 2 weeks (assuming she goes to school 5 days a week):
$1.25*10=$12.50
Now we find out how much she pays for the extra snack. Since in 2 weeks there are 2 Fridays then:
0.55*2=$1.10
Then we add these two together to get:
$12.50+$1.10=$13.60
Answer: 1 1/8 or 9/8
Step-by-step explanation:
5 1/2-4 3/8= 1/ 1/8
Answer: 4.6 cattle
Step-by-step explanation:
Since you are finding the average, you have to...
Step 1: Add all of the numbers:
4 + 1 + 9 = 14
Step 2: Divide 14 by 3 (the amount of numbers added)
14 ÷ 3 = 4.666666666667 (to be exact)

Answer:
x = -2.5 ± √14.25
Step-by-step explanation:
Add 5x to prepare for "completing the square."
x² +5x = 8
Add the square of half the x-coefficient:
x² +5x + 2.5² = 8 + 2.5²
(x +2.5)² = 14.25
Take the square root.
x +2.5 = ±√14.25
Subtract 2.5.
x = -2.5 ± √14.25 ≈ {-6.27492, 1.27592}
Ok let's start with question 1.
1. The equation is given. If she advices 360 people each week for 4 week she earns...
4(80+360(15)/100) = $536
2. In this problem instead of evaluating M we solve for n with M given.
140=80+15n/100
n=400 people
3. The new equation will still follow the same format.
M=65+21n/100
4. This will be the intersection point of the two lines. So when does...
80+15n/10=65+21n/100
We just have to solve for n.
-0.06n=-15
n=250 people
