Answer:
1. Total spent on transportation $222.2.
2. $ 192.5
3. She spends $30 over the guideline.
Step-by-step explanation:
As per the image attached:
Total monthly spent on transportation = Total monthly car payment + Spent on gas fuel
Total monthly spent on transportation = 120 + 37.9 + 28.4 + 35.9 = $222.2
So, Answer 1. Abby's total spent on transportation = $222.2
Calculating the percentage:
Calculating 11% as per the guideline:
Answer 2. As per the guideline, she should spend $192.5 on transportation.
Difference between spending and guideline = $222.2 - $192.5 = $29.7
Answer 3. She spends $29.7 over the guideline.
40 boys and 68 girls
let's start with variables and an equation.
boys: x
girls: 2x - 12
and we know that boys and girls make up the class. so let's add the two expressions.
x + 2x - 12 = 108
3x - 12 = 108
+ 12 + 12
3x = 120
x = 40 boys
BUT x is only the number of BOYS in the class. so we have to find girls now. let's plug in our value of x into the girls' equation.
2x - 12 = # of girls
2(40) -12 = # of girls
80 - 12 = # of girls
68 girls
let's check our answer!
68 + 40 does in fact add to 108, therefore our answer is correct.
Hello :
let : A(0,3) B(4,8)
<span>the slope is : (YB - YA)/(XB -XA)
</span>(8-3)/(4-0) = 5/4
same method for 4
£66 because 60/10=6 60+6= £66
8(4x+6y-2z)
32x+48y-16z
Hope this helps!
