Sara makes and sells bracelets. She bought material for $28.50 and used it all to make 15 bracelets. Sara used the equation to d
Norma-Jean [14]

Answer:

Sara should sell each bracelet at <em>$8.50</em> to make a profit of $99.

Step-by-step explanation:

We are given the following:

Total cost = $28.50

Total bracelets to be made = 15

Total profit to be made = $99

Let x be the price at which Sara sells each bracelet to make a profit of $99.

\text{Total sales done = Number of bracelets sold }\times \text{ Sales price of each bracelet}\\

\Rightarrow 15 \times x    ...... (1)

Also,

\text{Total sales price = Total Cost}+ \text{Total Profit} \\

\Rightarrow \$28.50 + \$99 ....... (2)

Equating (1) and (2):

\Rightarrow  28.50 + 99 = 15x\\\Rightarrow x = \dfrac{127.5}{15}\\\Rightarrow x = $8.50

Sara should <em>sell each bracelet at $8.50</em> to make a profit of $99.

Train A leaves Westtown and travels at 50 mph toward Smithville, 330 miles away. At the same time, Train B leaves Smithville and
lianna [129]
The answer to this question is that the trains will meet after 3 hours. We can work this out by considering that is the closing speed of the two trains is (50+60=)110 miles per hour, then this must mean that the combined distance that the trains need to travel before they meet is 330 miles. If the time that is taken to travel 330 miles at 110 miles per hour, then you simply need to divide 330/110 to find your answer - 3 hours.

Bailey has an hour to get ready for school. She spends 3/6 of the time getting dressed. She spends 1/4 of that time eating break
Katen [24]
Well, to find out whether she spent more time getting dressed or eating breakfast, we simply have to compare the fractions of the hour that she took on each.
We know that she took 3/6 of an hour to get dressed and 1/4 of an hour to eat breakfast. To find out which activity she spent more time on, we simply need to see which fraction is bigger.
To do this, we must first reduce the fractions to lowest terms. 1/4 is already in lowest terms, so we can leave that alone. 3/6 can be reduced, however, and since 3 goes into 6 twice, it reduces to 1/2.
Now, we can compare the fractions.
Is 1/2 of an hour or 1/4 of an hour more?
The answer is 1/2, so now we know that Bailey spent more time getting dressed than eating breakfast.
Hope that helped! =)
