If you look through the chart, you'll see that in each column,
the amount of money donated is 1/5 the number of lunch
specials sold.

The equation is:

Donation amount = (1/5) · (lunch specials sold) .

The constant of proportionality in money per lunch special sold
is $1/5 or 20 cents.

Phantasy [73]

Keywords:

<em>Medium sodas, buy, dollars, divide </em>

For this case we must find the amount of medium sodas that Natalie's group can buy, taking into account that they have 20 dollars and that each medium soda costs 1.25 dollars. To solve, we must divide:

Let "x" be the number of medium sodas you can buy, then:

$x = \frac {20} {1.25}\\x = 16$

So, Natalie's group can buy 16 medium sodas with 20 dollars

Wewaii [24]

Answer:

<h3> 26²/₃ liters of 15% acid and 13¹/₃ liters of 33% acid</h3>

Step-by-step explanation:

Concentration Amount of Amount

of Solution Solution (L) of Acid

15% x 0.15x

33% y 0.33y

21% 40 0.21•40

x + y = 40 ⇒ x = 40 - y

0.15x + 0.33y = 0.21•40

0.15(40 - y) + 0.33y = 0.21•40

6 - 0.15y + 0.33y = 8.4

0.18y = 2.4

y = 13¹/₃

x = 40 - 13¹/₃ = 26²/₃
