The sum of two numbers is 79. Three
Semmy [17]

Answer:

<u>The two numbers are 23 and 56</u>

Step-by-step explanation:

Let's say the two numbers are A and B.

We are told:

1)  A+B=79

2) 3A+5B=283

Let's take the first expression and solve for A:

A+B=79

A=79-B

Now use this value of A in the second expression:

3A+5B=283

3(79-B)+5B=283

237-3B+5B=283

2B = 46

B = 23

Since B=23, we know from 1) that

A+B=79

A+23=79

A = 56

<u>CHECK:</u>

Does A+B=79?  

        56+23 = 79?  <u>YES</u>

Does 3A+5B=283?

3(56)+5(23)=283

168  + 115 = 283?  <u>YES</u>

Total rental cost = $390 = 2($30/day) + ($0.25/mile)x     (x=number of miles)
                                                                                          330
Then 390 = 60 + 0.25x     =>    330 = 0.25 x    =>   x = ------------
                                                                                           0.25

x comes out to 1320 miles.
