So there are 8 stacks of 5 nickels which means that the equation would be simply 8 * 5 which equals 40 nickels. Then, 7 stacks of 6 dies would equal 42. Then she found one more dime and one more nickel which means she has 41 nickels and 43 dimes. In all, she has 84 dimes and nickels.

Pearl’s Biking Company manufactures and sells bikes. Each bike costs £40 to make, and the company’s fixed costs are £5000. In ad
LUCKY_DIMON [66]

Answer:

R(x) = £[300 - 2x²]

C(x) = £[5000 + 40x]

The breakeven points are when number of bikes manufactured is 21 or 239

Step-by-step explanation:

The company price function P(x) = 300 - 2x. x is the number of items that can be sold at $P per item.

The revenue is given as price per item × number of item sold.

Revenue R(x) = xP(x) = x(300 - 2x) = 300x - 2x²

R(x) = £[300 - 2x²]

The cost function [C(x)] is the sum of variable cost and fixed cost. Therefore:

C(x) = fixed cost + variable cost

Since the fixed cost is £5000 and  Each bike costs £40, this means that the variable cost = 40 × number of items manufactured = 40 × x = 40x

Therefore C(x) = £[5000 + 40x]

At breakeven point, the cost of producing an item is equal to the revenue (amount the item is sold) gotten from the item.

That is cost = revenue,

C(x) = R(x)

5000 + 40x = 300x - x²

x² - 300x + 40x + 5000 = 0

x² - 260x + 5000 = 0

x ≈ 239  or x ≈ 21. The breakeven points are when number of bikes manufactured is 21 or 239

Alex, Gil and Meg shared 740 cards. Alex had 20 fewer cards than Gil and
Ivan

Answer:

Step-by-step explanation:

A + G + M = 740

A = G - 20

A = M - 120

Therefore,

G = A + 20

M = A + 120

Plug it in...

A + (A + 20) + (A + 120) = 740

Combine like terms

3A + 140 = 740

- 140 -140

3A = 600

/3 /3

A = 200

Double check

A = 200, G = 220, M = 320

200 + 220 + 320 = 740
