What is the unit price for the cans of lemonade at each of the stores?

zvonat [6]

For shop smart, the price is 48 packs for 9 dollars so you would divide
9 ÷ 48 to find the price for dollars per can which is 19 cents per can
for super save it's saying 48 packs for 10 dollars so divide
10 ÷ 48 and that is 21 cents per can
for price buster it's saying 36 packs for 9 dollars so you would divide
9 ÷ 36 which is 25 cents per can
so Mei Pilar and David should purchase the cans at shop smart since it's cheaper

Lubov Fominskaja [6]

Answer:

$F = 1.8C +32$

$F = 86^{\circ}F$

Step-by-step explanation:

Represent Celsius with C and Fahrenheit with F.

So, we have:

$(C_1,F_1) = (100,212)$

$(C_2,F_2) = (0,32)$

Solving (a): Represent as a linear equation

First, we calculate the slope:

$m = \frac{F_2 - F_1}{C_2 - C_1}$

This gives:

$m = \frac{32 - 212}{0 - 100}$

$m = \frac{-180}{- 100}$

$m = 1.8$

The linear equation is then calculated using:

$F - F_1 = m(C -C_1)$

Where

$(C_1,F_1) = (100,212)$

$m = 1.8$

$F - 212 = 1.8(C -100)$

$F - 212 = 1.8C -180$

Make F the subject

$F = 1.8C -180+212$

$F = 1.8C +32$

Solving (b): The value of F when C = 30

Substitute 30 for C in $F = 1.8C +32$

$F = 1.8 * 30 + 32$

$F = 54 + 32$

$F = 86$

Help with math please???

Tresset [83]

Okay, let's see...

The problem is asking for a linear equation most likely in the form of y=mx+b

y is another way to say f(x)

<em>m = slope </em>

<em>b = y intercept </em>

Let's start with the y intercept first.

Y intercept means ' When does the line touch (intercept) the y axis.

In this case, if you look at the graph, the line <em>touches </em>the y axis at -1.

-1 will replaces b

To find the slope we are going to take 2 precise points from the graph.

Lets use <em>(0,-1)</em> and <em>(-6,4) </em>

To find the slope, we're going to use $\frac{(y_{2} -y_{1} )}{(x_{2} -x_{1} )}$

4 - (-1) / -6 - 0

Solve, our slope is 5/-6

That is our m

Our final equation is

$f(x)=\frac{-5}{6} x -1$

A discount of 16% saved Jackie $38 on office supplies. What was the price of the supplies before the discount?

zloy xaker [14]

16 % = 38

(16 × 6 = 96

16 / 4 = 4 so = 38/4 = 9.5)

100% = 38*5 + 9.5

=199.5
