A pair of basketball shoes's normal price is $120. Jordan bought it at a discount of 10%. He had to pay 8% tax on the discounted

Alekssandra [29.7K]

Answer:

$17.50

Step-by-step explanation:

If the shoes are discounted at 10%, the price would be 90% of the original price

Discounted price = 0.9 x 120 = 108

Tax increases the price of the good. so, the discounted price would increase by 8%

1.08 x 108 =116.64

If Jordan pays 15% as a down payment, he would pay :

0.15 x 116.64 = 17.496

A fisherman can row upstream at 2 mph and downstream at 8 mph. He started rowing upstream until he got tired and then rowed down

slega [8]

<h3>Answer: 16 miles</h3>

==========================================================

Explanation:

x = time in hours spent going upstream

5-x = remaining time in hours spent going downstream

Those two quantities add to 5 hours total.

Let's find the expression for how far the fisherman went upstream

distance = rate*time

d = r*t

d = 2x

Do the same for the downstream portion

d = r*t

d = 8(5-x)

d = 40-8x

The values of d refer to the same distance because he came back to the starting point.

Set those right hand sides equal to one another and solve for x.

2x = 40-8x

2x+8x = 40

10x = 40

x = 40/10

x = 4

5-x = 5-4 = 1

He spent 4 hours going upstream, and the remaining 1 hour coming back downstream.

--------------

If he spent 4 hours going upstream at 2 mph, then he traveled d = r*t = 2*4 = 8 miles.

The remaining 1 hour going downstream at 8 mph means he traveled d = r*t = 8*1 = 8 miles, which matches with the previous result. This confirms we have the correct one-way distance of 8 miles.

Therefore, the total round trip distance is 2*8 = 16 miles

exis [7]

Answer:

a) Write a let statement below to define your variable(s):

Let the number of fishes Ms. Montesinos has be represented by = f

b) Set up an equation using the variable you defined in (a):

The equation is :

3f - 2 = 13

c) Solve your equation & Check. How many fish does Ms. Montesinos have?

Ms. Montesinos has 5 fishes

Step-by-step explanation:

Ms. Cruz has a tank with 11 fish. After buying two more, she has 2 less than triple the amount of fish Ms. Montesinos has. How many fish does Ms. Montesinos have in her tank?

a) Write a let statement below to define your variable(s):

Let the number of fishes Ms. Montesinos has be represented by = f

b) Set up an equation using the variable you defined in (a):

We are told in the question:

Ms. Cruz has a tank with 11 fish. After buying two more, she has 2 less than triple the amount of fish Ms. Montesinos has.

Therefore,

3× f - 2 = 11 + 2

The equation is :

3f - 2 = 13

c) Solve your equation & Check. How many fish does Ms. Montesinos have?

Solving the above equation:

3f - 2 = 13

3f = 13 + 2

3f = 15

Divide both sides by 3

3f/3 = 15/3

f = 5

Hence, Ms. Montesinos has 5 fishes
