Carmen has $30 in store bucks and a 25% discount coupon for a local department store. What maximum dollar amount can Carmen purc
Klio2033 [76]

Answer:

$110.

Step-by-step explanation:

Let x be the cost of item that Carmen purchased from departmental store.

We are told that Carmen has $30 in store bucks and a 25% discount coupon for a local department store. We are asked to find the cost of Carmen's purchase so that after her store bucks and discount are applied, her total is no more than $60 before sales tax.  

As the $30 store bucks are applied before the 25% discount is applied, so we need to find x such that x-30 minus 25% of (x-30) should be less than or equal to 60. We can represent this information in an equation as:

x-30-((x-30)\times\frac{25}{100})\leq 60    

x-30-((x-30)\times 0.25)\leq 60

x-30-(0.25x-7.5)\leq 60    

x-30-0.25x+7.5\leq 60  

0.75x-22.5\leq 60  

0.75x-22.5+22.5\leq 60+22.5

0.75x\leq 82.5  

\frac{0.75x}{0.75}\leq \frac{82.5}{0.75}

x\leq 110    

Therefore, Carmen should make purchases at-most for $110 so that her total is no more than $60 before, sales tax.

<span>Using the formula above, your merit increase will be 2.5%. You received a score of 3.4 on your annual review. Since the merit increase model is 0.5% salary increase at a score of 2.6, with an additional 1% for every .4 points above that baseline, you get 2.5%, which is the baseline of 0.5% + 2% for the 0.8 points you scored above that baseline.</span>

Eli is making a party mix that contains pretzels and chex. For each cup of pretzels, he uses 3 cups of chex. How many cups of pr
Paha777 [63]
So for every one cup of pretzels (1p)
You have three cups of chex (3c)

The ratio between pretzels and chex is 1p:3c

Thus, changes in 1 is proportional with changes in 3.

You need a total of 12 cups of party mix. The sum of the ratio 1 cup of pretzels and 3 cups of chex is 4.

So you would need 3 cups of pretzels and 9 cups of chex for the ratio to equal a sum of 12.

Thus the answer is 3p:9c

almond37 [142]

Answer:

The electric bill of the Leonin family was of $ 877,626.

9.7514 x 90 = X

877.626 = X

Thus, the electric bill of the Leonin family was of $ 877.626.
