cost=cost per backetball times number of basketbals
cost=15 times b
cost≤130
15b≤130
divide both sides by 15
b≤8 and 10/15
b≤8 and 2/3
round down because you can't buy 2/3 basketball

Rhea is solving a math puzzle. To find the solution of the puzzle, she must find the product of two numbers. The first number is the sum of 23 and x, and the second number is 18 less than two times the first number. Which of the following functions represents the product of these two numbers?Opions are:

A.
P(x) = 2x^2 + 74x + 644
B.
P(x) = 2x^2 + 28x - 414
C.
P(x) = 2x^2 + 102x + 1,288
D.
P(x) = 2x^2 + 110x + 1,472

Answers

Answer:

It's B.

Step-by-step explanation:

First is x + 23 and second is 2x - 18.

So the product is

(x + 23)(2x - 18)

= 2x^2 - 18x + 46x - 414

= 2x^2 + 28x - 414

Of the 50 tables in a restaurant, 40% seat 2 people. The rest of the tables seat 4 people. How many seats are there in the restaurant?

Answers

For this case, the first thing we must do is determine the number of tables that 2 people sit.

For this, we use the following rule of three:

50 tables -----------------> 100%

x ----------------------------> 40%

Clearing x we have:

Then, the number of tables that 4 people feel is given by:

We are now looking for the number of chairs:

Table for 2:

Table for 4:

Total seats:

Answer:

there are 160 seats in the restaurant

40% of 50 is the same as 2/5 = 20 tables
20 x 2 = 40 seats

50 - 20 = 30 tables
30 x 4 = 120 seats

40 + 120 = 160 seats in total

Your bank gives you a special loan of $112,000. At the end of 30 years, you will pay the bank $176,400 in simple interest. What is the annual interest rate on your loan?

Answers

In the given problem there are several information's worth taking note of. Based on these information's the rate on the loan can be calculated.It is already given that the Principal amount is $112000. Time is given as 30 years and the final amount as $176400.
Now we have to find the amount of interest first
Interest amount = (176400 - 112000) dollars
   = 64400 dollars
As per the formula of simple interest we know that
Interest = Principal * Rate of interest * Time
Rate of Interest = (Principal * Time)/Interest amount
      = (112000 * 30)/64400
      = 3360000/64400
      = 52.17
So the rate of interest on the loan for the period of 30 years was 52.17%

Answer:

5.25
