fredd [130]

We can use the equations m + n = 18 and 1.25m + 0.75n = 19 to find number of each balloon for Myer

<u>SOLUTION: </u>

Given, Myers balloons cost $1.25 each, and latex balloons cost $0.75 each. We have to find what equations can be used to find the number of each of balloon in a bunch of 18 balloons that costs $19?

Let number of myers balloons be m, and number of latex balloons be n.

Then m + n = 18 ⇒ (1)

And according to given information,

$1.25 x number of myers ballons + $0.75 x number of latex balloons = $19

⇒ 1.25m + 0.75n = 19 ⇒ (2)

Hence, we can use the equations m + n = 18 and 1.25m + 0.75n = 19 to find number of each balloon.

Now, (1) ⇒ m = 18 – n. substitute these values in (2)

(2) ⇒ 1.25(18 – n) + 0.75n = 19

22.5 – 1.25n + 0.75n = 19

1.25n – 0.75n = 22.5 – 19

0.5n = 3.5

n = 7

Then, m = 18 – 7 ⇒ m = 11.

So, 11 myers balloons and 7 latex balloons.

Sergei estimated 149% of 67 by performing the following steps. Which statement is true?

enot [183]

Answer: Last option.

Step-by-step explanation:

In order to estimate the percent "n" of a number"x", you need easy numbers to work with, therefore you can round "n" and "x" up or down; but it is important to remember that this estimation does not give you an exact value.

You can observe that Sergei's first step was to round 149% and 67 up, getting this result:

$=105$

To verify if this estimate is less or greater than the actual answer, we can find the actual answer. This is:

$\frac{67*149}{100}=99.83$

Therefore, we can conclude that<em> the estimate is greater than the actual answer because the percent and the number were both rounded up</em>.

The regular price of a shoe is $48. The store is having a buy one get one 1/2 off sale. If you buy 2 pairs of shoes for that pri

Ulleksa [173]

Answer:

25% discount

Step-by-step explanation:

48*2=96

However, instead one pair is 50% off. So, one pair will be $48 and another will be $24. So, if you purchase two pairs, you only have to pay$72. 72/96=.75. This means you are paying for 75% of the original price, meaning you got 25% off discount.
