1.1 PRACTICETRIP TO ENGLAND

ANSWERS

1.

The trip is 90 days

3 weeks in France and Spain is 21 days.

The rest is in England

90 – 21 = 69 days.

2.

Each day in England costs $240

The total cost in England is

240 x 69 = $16 560

3.

Huia saves 2/5 of $850

2 ÷ 5 x 850 = $340

Mike saves 35% of $790

35 ÷ 100 x 790 = $276.5

Total savings

340 + 276.5 = $616.5

4.

Ticket cost is $2500 plus 15%

15 ÷ 100 x 2500 = 375

2500 + 375 = $2875

Mike pays the whole cost

5.

Huia’s ticket is split by the ratio of 1:4

Huia pays only 4/5

4 ÷ 5 x 2875 = $2300

Total ticket price

2875 + 2300 = $5175

Number of Weeks

Total Cost

$29 535

Total savings per week

340 + 276.5 = $616.5

Number of Weeks

29 535 ÷ 616.5 = 47.9 weeks

This means that they will have saved enough after 48 weeks.

Options

3 months is not actually 90 days

It can be as low as 89 days or as high as 92 days.

This means the trip could be from $240 cheaper to $480 dollars more expensive.

This means the most the trip could cost is

29535 + 480 = $30 015

This takes

30015 ÷ 616.5 = 48.7 weeks

This means they will have saved enough after 49 weeks.

And the least the trip could cost is

29535 - 240 = $29 295

This takes

29295 ÷ 616.5 = 47.5 weeks

This means they will have saved enough after 48 weeks. The same as if the trip really was 90 days.
