P = pizza and c =cakes

Last week: 8p + 13c = 134
Today: 28p + 4c = 220

Let’s take the formula for today and subtract 28p from each side to isolate the 4c.

4c = 220 - 28p

Now divide each side by 4

c = (220 - 28p)/4
Simplify to c = 55 - 7p

Now go to the formula for last week, substitute the c for 55-7p

8p + 13(55 - 7p) = 134
8p + 715 - 91p = 134

Simplify to 715 - 83p = 134

Let’s add 83p to each side.

715 = 134 + 83p

Subtract 134 from each side

581 = 83p

Divide each side by 83

p = $7

2x+3=9 what is the answer

xxMikexx [17]

Answer : x=3

Step-by-step explanation:

Explanation:

2x+3=9

We want to find the variable x, so we have to make it alone. To do so, first subtract 3 from both sides of the equation:

2x+3 − 3=9 − 3

2x=6

Now divide both sides by 2:

2x2=62

So the final answer is:

x=3

What is the simplified form of 72x16/50x36 ? Assume x ≠ 0.

AleksandrR [38]

72 / 50 = 36/25

x^16 / x^36

= x^-20

simplified form is 36 / 25x^20

Mr smith earn 1900 each week and his wife earns 1150 each week they need to set aside 300 for food 90 for gas 875 for the mortga

QveST [7]

answer

1385

explanation

to find the total, subtract the amount they earned by the amount they spend

total = earned - spent

earned

each week, Mr. Smith earns 1900 and and his earns 1150, so add these values together to find the total amount they earn

earned = 1900 + 1150

earned = 3050

spent

they spend money on food, gas, mortgage, and savings, so add these values together to find the total amount they spend

spent = food + gas + mortgage + savings

spent = 300 + 90 + 875 + 400

spent = 1665

total

now that we know how much they earn and spend, we can find the total

total = earned - spent

total = 3050 - 1665

total = 1385

every week they have 1385 left over

Cost, Revenue, and Profit A company invests $98,000 for equipment to produce a new product. Each unit of the product costs $12.2

Vesnalui [34]

Given:

Investment on equipment = $98,000

Cost of each unit = $12.20

Selling price of each unit = $16.98.

To find:

(a) The total cost C as a function of x.

(b) The revenue R as a function of x.

Solution:

Let x be the number of units produced and sold.

We have,

Fixed cost = $98,000

Variable cost = $12.20x

Total cost = Fixed cost + Variable cost

$C(x)=98000+12.20x$

Therefore, the cost function is $C(x)=98000+12.20x$ .

Selling price of each unit = Revenue from each unit = $16.98.

Total revenue = Revenue from x units

$R(x)=16.98x$

Therefore, the revenue function is $R(x)=16.98x$ .

Profit = Revenue - Cost

$P(x)=R(x)-C(x)$

$P(x)=16.98x-(98000+12.20x)$

$P(x)=16.98x-98000-12.20x$

$P(x)=4.78x-98000$

Therefore, the profit function is $P(x)=4.78x-98000$ .
