Colin invests £2350 into a savings account. The bank gives 4.2% compound interest for the first 4 years and 4.9% thereafter. How much will Colin have after 10 years to the nearest pound?​

Answers

Answer:

£3,692

Step-by-step explanation:

First four years

A = p(1 + r/n)^nt

P = £2350

r = 4.2% = 0.042

n = 1

t = 4

A = p(1 + r/n)^nt

= 2350(1 + 0.042/1)^1*4

= 2350(1 + 0.042)^4

= 2350(1.042)^4

= 2350(1.5789)

= 2770.42

A = £2770.42

Next 6 years

P = £2770.42

r = 4.9% = 0.049

n = 1

t = 6

A = p(1 + r/n)^nt

= 2770.42(1 + 0.049/1)^1*6

= 2770.42(1 + 0.049)^6

= 2770.42(1.049)^6

= 2770.42(1.3325)

= 3691.59

A = £3691.59

Approximately £3692

Lia has a goal of walking at least 20 miles. She walks at a rate of 5 miles per hour. Which inequality can Lia use to find h, the number of hours she should walk in order to meet or exceed her goal? A. 5h ≥ 20 B. 5h ≤ 20 C. H+5 ≥ 20 D. H+5 ≤ 20

Answers

Answer:

5h ≤ 20 or h ≤ 4

Step-by-step explanation:

Lia walks at a rate of 5 miles per hour.

Lia has a goal of walking at least 20 miles

Let h be the number of hours she should walk in order to meet or exceed her goal.

At least in inequality means ≤. ATQ,

5h ≤ 20

Dividing both sides by 5.

h ≤ 4

So, she should walk atleast 4 hours. Hence, the correct option is (b).

Karen rented a truck for one day. There was a base fee of $12.00, and there was an additional charge of 6 cents for each mile driven. The total cost, C (In dollars) for driving x miles is given by the following. C=12.00+0.06x what is the total rental cost if Karen drove 40 miles?

Leasing companies purchase capital equipment, like airplanes or trucks, and then lease the equipment to the firms that actually use them. On its face, it is hard to see why this is a wealth-creating transaction since the end users could borrow money and purchase their own equipment. The answer is that banks, due to the way they are regulated, are more willing to lend to companies with less debt. By leasing equipment, a company moves debt off its balance sheet, which makes it easier to borrow more heavily. The enhanced borrowing ability of low-debt companies makes leasing more valuable than borrowing and buying. In the fall of 2015, one such truck leasing company was having trouble making money. The company purchased over-the-road trucks for $92,000 and then leased them to various transport companies, ranging from small owner-operators to large publicly owned firms with fleets of over hundred trucks.
