Mr. Lincoln buys juice and water for the school picnic. A pack of 8 juice boxes ca
alexgriva [62]

Answer:

5x + 3y = 95

8x + 6y = 170

x = 10 ; y = 15

Step-by-step explanation:

Let :

x = pack of juice boxes

y = pack of water bottles

Pack of juice box = $5

Pack of water bottles = $3

Amount of money spent :

5x + 3y = $95

Number of drinks purchased :

8x + 6y = 170

Using both equations ;

5x + 3y = 95 - - - (1)

8x + 6y = 170 - - - (2)

Multiply (1) by 6 and (2) by 3

30x + 18y = 570

24x + 18y = 510

Subtract :

6x = 60

x = 60 / 6

x = 10

Put x = 10 in (1)

5(10) + 3y = 95

50 + 3y = 95

3y = 95 - 50

3y = 45

y = 45 / 3

y = 15

x = 10 ; y = 15

I NEEEEEED HEEEEEEEP PLZZZZZZZZ
Tema [17]

So, since the student makes $30 each week, we can disregard the number of hours.


So, we can model this situation by the following equation

9.5h+30


So, if he works 10.25 hrs (15 minutes = .25 of 1 hr) we just plug that number in

9.5h+30\\9.5(10.25)+30\\127.275

Since it's money we round to the nearest cent

So he will make $127.28 Next week
