Answer:
Discount before the Coupon
Step-by-step explanation:
The cost of two paperbacks at $8 each=2 X $8 =$16
First, we determine for the case in which the coupon is applied first.
If the $4 Coupon is applied,
Cost=$16-$4 = $12
If the 10% discount is further applied,
Amount to be paid = $12-(10% of $12) =$12-1.2= $10.8
However if the discount is applied first,
Book Cost=$16-(10% of $16)=16-1.6=14.4
If the Coupon is then applied,
Amount to be paid= $(14.4-4)=$10.4
Since $10.4 is less than $10.8, we conclude therefore that it is less expensive to apply the discount first.
129,407
12 ten thousands is 120,000
8 thousand is 8,000
14 hundreds is 1,400
there are no tens
7 ones is 7
so 120,000+8,000+1,400+7=129,407
Answer:
<u>Definitions of the variables in the situation:</u>
J = Jana's age
S = Sister's age
<u>The Equation:</u>
J + 8 = S
Step-by-step explanation:
<u>Explanation: </u>
In the equation we will use the variable J for Jana and S for Janna's sister. Since we know Jana's age plus 8 equals her sister's age, the equation will be J + 8 = S
Answer:
No, a reasonable estimate is around 6 times $7 = $42
Step-by-step explanation:
$6.99 is rounded up to 7, and there are 6 people who ordered a $7 meal. And 6 times 7 is 42
Answer:
y = -2x + 2
Step-by-step explanation:
Given the following data;
Points on the x-axis (x1, x2) = (2, -1)
Points on the y-axis (y1, y2) = (-2, 4)
To find the equation of line in slope intercept form;
First of all, we would determine the slope of the line.
Mathematically, slope is given by the formula;
Substituting into the equation, we have;
Slope, m = -2
Next, we would use the following formula to find the equation of the line;
y - y1 = m(x - x1)
Substituting into the formula, we have;
y - (-2) = -2(x - 2)
y + 2 = -2x + 4
y = -2x + 4 - 2
y = -2x + 2 = mx + c
