Answer:
Step-by-step explanation:
Q1
(16.75*1.065)*(1.15)=21.52. Tax comes before tip so has to be done in that order. Hope it helps.
Q2
C. is the correct answer. To work it out for yourself just work out what 10 percent is and then half that. IE. 5 percent and add the two figures together.
Q3
16.75*1.15*1.065
=20.5145625
=20.51
therefore, the closest answer is B
Q4
The sales tax rate is 7.25%.
Cost of messenger bag = $52.50
Kevin will pay sales tax = 7.25% of 52.50
= \frac{7.25}{100}\times 52.50
= 0.0725 × 52.50
= $3.80625 ≈ $3.81
Kevin will pay $3.81 sales tax on messenger bag
Q5
D. 20%
$15 x .2= $3
if you didn't have the options you could do
3/15=.2
Q6
x = (38.99) (.25) x = 9.75 Then; x = $38.99 - $9.75 x = $29.24 Bobbi needs to pay $29.24 for the shirt.
Q7
3.65 + 4.25 + (0.99 x 3) + 6.75 = 17.62
5.5% = 0.055
17.62 x 0.055 = 0.97
17.62 + 0.97 = 18.59
Q8
Shawn would leave $6.84 for a tip. Solution: 15% = 0.15 0.15 * $45.60 = $6.84
Q9
26.95 * x = 21.56
x = 21.56/26.95
x = 0.8
x = 80%
=> 100% - 80% = 20%
Q10
75................100%
(88.5-75)........x
x=(13.5*100):75
x=1350/75
x=18
Answer: 18%
Let x=Don's present age
2x=Chris's present age
next year:
<span>x+1=Don's age
</span><span><span>2x+1=Chris's age
(x+1)+((2x+1)=4(x-1) (next year the sum of their ages will be four times as much as Don's age last year.)
x+1+2x+1=4x-4
x=6
2x=12
Don's present age=6
Chris's present age=12 </span><span>
</span></span>
OK. Here we go:
Step #1: Write the equation on your paper.
Step #2: Add 3 to each side of the equation.
Step #3: With the result of step-#2, divide each side of the equation by 2.
If your result of step-#3 is not 4.5, then go back to step-#1, and go through
all 3 steps again, trying to be more careful and focused.
