$4 + $9 = 13
Answer: Plan A is cheaper, because the cost of a 2-minute call and a 4-minute call is less than the cost of a 2-minute call and a 4-minute of Plan B call.
Step-by-step explanation:
1. You have the following information of Plan A:
- A 2 minute call costs .54 cents.
- A 4 minutes call costs $1.08.
2. For Plan B, you know that the cost of 
is given by the equation:
3. Therefore, you can compare both plans by finding the cost of a call of 2 minutes and a call of 4 minutes of Plan B. You can calculate this by giving these values to :
4. Substitute the values into the equation:
(This is more expensive)
(This is more expensive)
5. Therefore, Plan A is cheaper, because the cost of a 2-minute call and a 4-minute call is less than the cost of a 2-minute call and a 4-minute of Plan B call.
Answer:
$344.04
Step-by-step explanation:
The markdown multiplies the price by (1 -40%) = 0.60.
The tax multiplies the price by (1 +10%) = 1.10.
The two factors applied to the price make the final price be ...
$521.28·0.60·1.10 = $344.04
The total cost of the surfboard was $344.04.
Answer:
I am not sure if my math is correct but I got $15 dollars in change.
Step-by-step explanation:
$50 times 0.10 (10%) equals $5. $50.00 minus $30.00 is $20.00. $20 minus $5 is $15.
Let's do this in steps, show your work! | <em>Make sure to ask questions!</em>
#1. Simplify 5x - 4 + 3 to 8x - 4.
<u>8x - 4 = 36.</u>
#2. Add 4 to both sides.
<u>8x = 36 + 4. </u>
#3. Simplify 36 + 4 to 40.
<u>8x = 40.</u>
#4. Divide both sides by 8.
<u>x = 40/8.</u> <------ <em>It turned into a fraction because it's easier to not divide a decimal. </em>
#5. Simplify 40/8 to 5.
<u>x = 5. </u>
<h3>Therefore, x = 5.</h3>
