Answer:
38.88
Step-by-step explanation:
B + (-60) = -14
-60 -60
---------------
b = -74
What error, if any, did Maureen make?
Maureen's work is correct, and her original balance was -$74.
Maureen should have added 60 to both sides.
Maureen should have added 14 to both sides.
Maureen made a computational error when she subtracted -14 - 60
Maureen's work is correct, and her original balance was -$74.
--> Maureen should have added 60 to both sides.

The quantities in the proportion you give add to 16 pounds, of which 2 pounds are cement. That is, cement constitutes 1/8 of the total weight.
For each yard of concrete, 4000 lb/8 = 500 lb of cement are used.
For 12.5 yards of concrete, 12.5 * 500 = 6,250 pounds of cement will be used.
_____
"yard" in this case is shorthand for "cubic yard".
y = 25 + 0.15x is the equation for relating the cost y to the number of miles x that you drive the car
<em><u>Solution:</u></em>
Let "y" be the total cost of car rental
Let "x" be the number of miles you drive the car for more than 100 miles
<em><u>A car rental firm has the following charges for a certain type of car:</u></em>
$25 per day with 100 free miles included, $0.15 per mile for more than 100 miles
<em><u>Suppose you want to rent a car for one day, and you know you'll use it for more than 100 miles</u></em>
Therefore,
Car is rented for one day
You will use it for more than 100 miles
Therefore, equation is framed as:
Total cost = $ 25 + 0.15(number of hours)

Thus the equation for relating the cost y to the number of miles x that you drive the car
Answer:
Step-by-step explanation:
Average amount saved per year = 
=$
So on average Joanne has saved $3000 per year. She only needs $2000 more which will not even take a year to save.
How many months it will take to save $2000:

=
Months.
It will only take Joanne 8 moths to save $2000.
If she really wants to buy the home now she can always go for a home loan scheme for $2000. Any interest rate less than 50% per year is fine as she can save $3000 per year.
