Mimi sells super-sized cookies for $1.50 each and estimates she has expenses of $10 to make one batch of cookies. If the inequal

Jobisdone [24]

Answer:

(b) x > 26 cookies

Step-by-step explanation:

The selling price of 1 super-sized cookie, S.P.=$1.50

Let a batch have x cookies.

So, the selling price of x cookies=1.5x

The expences in making one batch of cookies=$10

So, net profit = 1.5x-10

The given inequality to model this is 1.5x - 10 > y, That means the profit for one batch is greater than y.

As she wants to make a profit of at least $30, so for this condition, the value of y is 30.

Now, the given inequality become,

$1.5x - 10 >30$

$\Rightarrow 1.5x>30+10$

$\Rightarrow x>\frac{40}{1.5}$

$\Rightarrow x>26\frac{2}{3}$

As x is the number of cookies, so, it can't have a fractional value. This can be written as

$x>26$ or $x\geq27.$

So, she has to sell more than 26 cookies to make a profit of at least $30.

Hence, option (b) is correct.

Answer:

x = 10

Step-by-step explanation:

Use CPCTC (Corresponding parts of congruent triangles are congruent).

Set the ratios:

$\frac{6.5}{5} = \frac{6.5 + 6.5}{x}$

First, simplify. Combine like terms:

$\frac{6.5}{5} = \frac{13}{x}$

Next, cross multiply.

$5 * x * \frac{6.5}{5} = \frac{13}{x} * x * 5\\x * 6.5 = 13 * 5\\6.5x = 65\\$

Isolate the variable, x. Divide 6.5 from both sides of the equation:

$\frac{(6.5x)}{6.5} = \frac{(65)}{6.5} \\\\x = \frac{65}{6.5}\\x = 10$

Check:

$\frac{5}{6.5} = \frac{x}{13}$

Plug in 10 for x (Your answer). Cross multiply, then simplify:

$\frac{5}{6.5} = \frac{10}{13}$

$13 * 6.5 * \frac{5}{6.5} = \frac{10}{13} * 13 * 6.5$

$13 * 5 = 10 * 6.5$

$65 = 65$ (True).
