Match the real-world problem to its constant of proportionality.

OleMash [197]

Answer:

6.12

1.39

4.12

12

Step-by-step explanation:

If y ∝ x, then y = kx.

So, the constant of proportionality is given by $k = \frac{y}{x}$

Case 1:

$18.36 for 3 pizzas

Therefore, the constant of proportionality is $\frac{18.36}{3} = 6.12$

Case 2:

$4.17 for 3 pounds of bananas.

Hence, the constant of proportionality is $\frac{4.17}{3} = 1.39$

Case 3:

$16.48 for 4 pounds of potatoes.

Hence, the constant of proportionality is $\frac{16.48}{4} = 4.12$

Case 4:

2 cups of flour to make 24 cookies.

Hence, the constant of proportionality is $\frac{24}{2} = 12$ (Answer)

almond37 [142]

Answer: £23,360

Step-by-step explanation:

You can use algebra to solve this.

Assume that the original investment is x.

In the beginning of 2015 the balance had increased by 2.5% which is denoted as:

= 1.025x

Carol then withdrew a thousand:

= 1.025x - 1,000

This value then increased by 2.5% again by the beginning of 2016:

= 1.025 * (1.025x - 1,000)

Relevant expression therefore is:

1.025 *(1.025x - 1,000) = 23,517.60

1.025x - 1,000 = 23,517.60/1.025

1.025x = ‭22,944‬ + 1,000

x = 23,944/1.025

x = £23,360
