Neal decides to sell his concert tickets to a sold- out show. He paid 90$ for the pair but believes he can sell them for 150% of
Pie

Answer:

Neal thinks that he can sell the tickets for $135.

Step-by-step explanation:

Original price at which Neal bought the tickets = $90

If he expects to sell them at 150% of the original,

150% as a decimal = 150/100 = 1.5

the new resale price = 1.5* $90

                                   = $135

Therefore, Neal thinks that he can sell the tickets for $135.

Daniel is planning a 6-night road trip. It will cost $310 for transportation, $275 for food, and $70 per night for a hotel room.
Anna11 [10]

Answer:

Daniel must tutor 160 hours

Explanation:

310+275+70= 655

655×6= 3930 (he needs this amount of $)

(Daniel gains $20 per hour)

20×160= 3200

3200+745= 3945

3945 > 3930

Daniel has enough for the trip.

Where did I get 160?

Well, I was just trying out numbers and multiplying it by 20

The numbers I tried: 100, 150, 156, 159 & 160 but only 160 fit with the answer.

If it was just one night road trip he would've just needed $655, but since it's a 6-night road trip I multiplied it by 6.

Hope this helped!

19. A teacher tells 36 students to form 4 equal groups. Write and solve a
olchik [2.2K]

4 x = 36

Step-by-step explanation:

Because the groups have an equal number of students, we assume that each of the groups has <em>x </em>number of students.

Therefore since there is <em>x</em> number of students in each of the 4 groups, there is 4 * x number of total students in all groups combined.

Since the question already indicates that there are a total of 36 students in the class, then we can indicate that..

4x = 36
