A school goes through 10 gallons of milk in 3 days.

Akimi4 [234]

G = gallons d = days
10g = 3d
?g = 1d
1g = ?d
-------------
for gallons in a day, divide 10g = 3d by 3
d = 10/3 gallons
3 and 1/3 gallons in a day
---------------
for days per gallon, divide 10g = 3d by 10
g = 3/10 days
1 gallon lasts 3/10 of a day

Benito’s family is thinking of relocating from Los Angeles to Oakland to save money. They set up a budget comparing the cost of

zmey [24]

Total monthly saving = $1,315

<h3>What are savings?</h3>

Saving is the portion of income not spent on current expenditures. In other words, it is the money set aside for future use and not spent immediately.

Given:

Oakland Los Angeles

Cost Housing $565 $1200

Food $545 $655

Health Care $245 $495

Taxes $450 $625

Other Necessities $350 $495

Now,

Saving in house

= $1200 - $565

= $635

Saving in food

= $655 - $545

= $110

Saving in health care

= $495 - $245

= $250

Saving in taxes

= $625 - $450

= $175

Saving in necessities

= $495 - $350

= $145

Total saving = $635+$110+$250+$175+$145

= $1,315

Hence, the monthly savings should be $1,315.

Brianna's family spent $134 on 2 adult tickets and 3 youth tickets at an amusement park. Max's family spent $146 on 3 adults tic

Firdavs [7]

The price of 1 youth ticket is $ 22

Solution:

Let "y" be the price of 1 youth ticket

Let "a" be the price of 1 adult ticket

To find: price of 1 youth ticket

Brianna's family spent $134 on 2 adult tickets and 3 youth tickets at an amusement park

So we can frame a equation as:

2 adult tickets x price of 1 adult ticket + 3 youth tickets x price of 1 youth ticket = 134

$2 \times a + 3 \times y = 134$

2a + 3y = 134 ---- eqn 1

Max's family spent $146 on 3 adults tickets and 2 youth tickets

So we can frame a equation as:

3 adult tickets x price of 1 adult ticket + 2 youth tickets x price of 1 youth ticket = 146

$3 \times a + 2 \times y = 146$

3a + 2y = 146 ----- eqn 2

Let us solve eqn 1 and eqn 2 to find values of "y"

Multiply eqn 1 by 3

6a + 9y = 402 ---- eqn 3

Multiply eqn 2 by 2

6a + 4y = 292 ----- eqn 4

Subtract eqn 4 from eqn 3

6a + 9y = 402

6a + 4y = 292

( - ) -------------------

5y = 110

y = 22

Thus the price of 1 youth ticket is $ 22
