Which of the following is the solution of 0.125x+1-0.25x<-3

Answers

Step-by-step explanation:

To find the solution to the inequality 0.125x + 1 - 0.25x < -3, we can simplify and solve for x.

0.125x + 1 - 0.25x < -3

Combining like terms:

-0.125x + 1 < -3

Subtracting 1 from both sides:

-0.125x < -4

Now, to isolate x, we divide both sides by -0.125. However, since we are dividing by a negative number, we need to reverse the inequality sign:

x > -4 / -0.125

Simplifying the division:

x > 32

Therefore, the solution to the inequality 0.125x + 1 - 0.25x < -3 is x > 32.

Ray Cupple bought a basic car costing $26,500.00, with options costing $725.00. There is a 6% sales tax in his state and a combined $50.00 license and registration fee. What was Ray's total cost?A. $28,865.00
B. $28,911.50
C. $27,275.00
D. $28,908.50

Answers

Answer: D. $28,908.50

Step-by-step explanation:

Given: Cost price of car= $26,500

Cost of options= $725

Therefore, the total cost=$26,500+ $725=$27225

As there is a 6% sales tax in his state .

⇒ Tax amount = 6% of Total cost

$=0.06*\$27225=\$1,633.5$

⇒Tax amount=$1,633.5

Combine $50 licence, registration fee and tax amount to the total cost , we get

Total cost=$27225+$1,633.5+$50

∴Total cost=$28,908.5

Adding the basic car costing and the additional options costing, we have (26500 + 725) = $ 27 225. Since sales tax is to be included for the payment, Ray must pay for 1.06 of the basic cost. Which is equal to 1.06(27 225) = $ 28 858.50 Adding the license and registration fee into the price, we have $28 908.50. Hence, the total cost is D: $28, 908.50.
