Roger brought some sponges. The number of packages he bought was 14 less than the number of sponges per package. Roger bought 51
mihalych1998 [28]

Answer:

the number of sponges per package bought be 32.5

Step-by-step explanation:

Let us assume the number of sponges per package be x

So the number of packages he bought be x - 14

And, the overall he bought 51 sponges

So

the number of packages of sponges did roger buy is

x + x - 14 = 51

2x = 51 + 14

2x = 65

x = 32.5

So the number of sponges per package bought be 32.5

Ian's parents asked him to creat a budget for his $ 1,000 monthly income . He determines that he would like to save the remainin
Kay [80]

35%

First, we need to find the amount of money that is being spent. Add all of the amounts together.

$350 + $100 + $120 + $80

$450 + $120 + 80

$570 + $80

$650

So, Ian spends $650 of his budget each month. How much does that leave for savings? Just subtract $650 from $1,000 to find that he saves $350 each month.

Now, you just need to find the percentage. The percentage is the same as the numerator in a fraction with a denominator of 100, so x% = x/100. For example, 1% = 1/100. $350 / $1000 = x / 100

How do we turn 1,000 into 100? Divide it by 10. And if you do something to the denominator of a fraction, you have to do it to the numerator as well. So, divide $350 by 10 and divide $1000 by 10, leaving you with $35 / $100 = x / 100

Multiply both sides by 100 to get x by itself. This leaves you with 35 = x, so 35% of Ian’s budget with go towards saving.

Company earns S dollars by selling y items per week. According to the equation S(y)=−2y^2+60y+10, how many items does company ne
sp2606 [1]

Answer:

Max = 15

Step-by-step explanation:

Given

s(y) = -2y^2 + 60y + 10

Required

Determine number of items that gives maximum earnings;

The general form of a quadratic equation is:

s(y) = ay^2 + by + c

And the maximum is calculated as:

Max = \frac{-b}{2a} If a<0

Comparing s(y) = ay^2 + by + c to s(y) = -2y^2 + 60y + 10

We have that:

a = -2     b = 60   c = 10

Substitute these values to

Max = \frac{-b}{2a}

Max = \frac{-60}{2 * -2}

Max = \frac{-60}{-4}

Max = 15

<em>The number of item that maximizes the function is when y = 15</em>
