Answer:

$27.71

Step-by-step explanation:

Price of 1 DVD: $9.19

Price of 4 DVDs: 4 * $9.19 = $36.76

Discount: 25%

Now we find 25% of $36.76.

25% of $36.76 =

= 0.25 * $36.76

= $9.19

The 25% discount amounts to $9.19. We now subtract $9.19 from $36.76 to find the discounted price.

$36.76 - $9.19 = $27.57

Now we need to apply the 7.75% tax to $27.57.

7.75% of $27.57 =

= 0.0775 * $27.57

= $2.14

The sales tax is $2.14.

Now we add the sales tax amount to the total discounted price.

$27.57 + $2.14 = $29.71

Answer: $27.71

Bobby wants to go on a school trip that will cost him $250. He comes up with an equation that represents how much he needs to sa

monitta

Yes, Bobby will have enough money if he saves for 9 weeks. You can find this through either substituting w for 9 in the equation, or solving the equation itself.

Substituting:

$25(9)+30$
Substitute w for 9.

$225+30$
Simplify.

$225+30=255$
Solve.

255 is greater than 250, so yes, he will have enough money saved.

Solving the equation:

$25w+30=250$
Original Equation

$25w=220$
Subtract 30 from both sides.

$w=8.8$
Divide both sides by 25.

The number of weeks he needs is 8.8. When rounding it up, you get 9.

Sum of interior angles of a △ = 180°

∴ ∠T + ∠V + ∠U = 180°

⇒ 37° + 63° + X° = 180°

⇒ X° + 100 = 180°

⇒ X° = 180° - 100°

⇒ X° = 80° (D).

Jimmy made a trip to the ferry office and back. The trip there took two hours and the trip back took three hours. He averaged 20

sukhopar [10]

Answer:

60 mph

Step-by-step explanation:

We don't know how far Jimmy drives in each direction. Let this distance be d. Then, d = rate * time, and d = r(2 hours) (where r represents his speed while driving to the ferry).

But it's also true that d = (r - 20 mph)(3 hours).

Equating d = r(2 hours) and d = (r - 20 mph)(3 hours), we get:

r(2) = (r - 20)(3), or 2r = 3r - 60.

Subtracting 2r from both sides yields 0 = r - 60, so that r = 60 mph.

Jimmy averaged 60 mph on the outbound trip.
