Ok so 30% as a decimal would be .3 so you have to multiply .3 by 315 and you will get 94.5 wich is how much is discounted off. so now subract 94.5 from 315 and that is 220.50 and that is the price hope this helps

The original price was 409.5 because 30% of 315 equals 94.5 so that was what they subtracted from 315 so to know the original price you add 94.5 to 315 and the answer is 409.5

There are 24 pens in a desk drawer. The pens are either red or blue. The ratio of red pens to blue pens is 5:1. How many pens ar
Flura [38]

Answer:

The number of red pens is 20.

The number of blue pens is 4.

Step-by-step explanation:

We are given that, the ratio of number of red pens to the number of blue pens is 5 : 1.

∴ Let us assume that the number of red pens be 5<em>x</em> and number of blue pens be <em>x</em>.

Total number of pens in the desk drawer = 24

Now, according to question :

Number of red pens + Number of blue pens = 24

⇒5<em>x</em> + <em>x</em> = 24

⇒6<em>x</em> = 24

⇒x=\frac{24}{6}=4

So, number of red pens in the drawer = 5<em>x</em> = 5 × 4 = 20

Number of blue pens in the drawer = <em>x</em> = 4

valina [46]

Answer:

140 + 96 m

Step-by-step explanation:

There are 4 weeks in 1 month.

Therefore:

Jonny has $50 in a savings account. Each week, he deposits $13 in the account.

$50 + $13 × 4m

The algebraic expression is given as:

50 + 52m

Jonny's brother has $90 in a saving account.

Each week, he deposits $11 in the account.

The algebraic expression is given as:

$90 + $11 × 4m

90 + 44m

An algebraic expression to describe how much money Jonny and his brother will have in their accounts after m months is written as:

Amount Jonny has + Amount his brother has

50 + 52m + 90 + 44m

= 50 + 90 + 52m + 44m

= 140 + 96 m

Choose the word phrase (greater than, less than, or equal to) to make the statements true.
d1i1m1o1n [39]

Answer:

Five pencils and two marches are worth greater than thirty paper clips.

Step-by-step explanation:

Let 'x' be paper clip.

Let 'y' be a match

and let 'z' be a pencil.

Now, let's write each statement as an equation:

Each paper clip can be traded for three matches:

x = 3y

Each pencil can be traded for six paper clips:

z = 6x

Now, five pencils equals 30 paper clips and two matches equals two thirds papel clips.

Therefore, we can say that Five pencils and two matches equals 30.66 matches. Therefore, five pencils and two marches are worth greater than thirty paper clips.
