Answer:

The cost of each park per day are:

Busch gardens: $80.45 per day

Universal Studios: $81.86 per day

Explanation:

To solve this, first, we have to use the ratio of days given to calculate the specific amounts for each park. this is calculated thus;

a. 2 days at Busch gardens and 3 days at Universal = $420

Cost ratio of Busch gardens to Universal = 2:3. meaning that out of the cost in 5 parts, Busch gardens takes 2 parts, while Universal takes 3 parts

Therefore actual prices are;

Busch gardens; 2/5 × 420 = $168 (2 days)

Universal studios; 3/5 × 420 = $252 (3 days)

The same calculation is done for the second statement

Busch gardens; 4/6 × 427 = $314.7 (4 days)

Universal studios; 2/6 × 472 = $157.3(2 days)

Next, let us add the total number of days and amount for each park;

Busch gardens; 2 days = $168; 4 days; $314.7

∴ 2 days + 4 days = 6 days = 168 + 314.7 = $482.7

Universal studios; 3 days = $252; 2 days = $157.3

∴ 3 days + 2 days = 5 days = 252 + 157.3 = $409.3

Finally to find the cost per day, let us divide the total cost by the total number of days;

Busch gardens;

6 days = $482.7

∴ 1 day = 482.7 ÷ 6 = $80.45

Universal studio;

5 days = $ 409.3

∴ 1 day = 409.3 ÷ 5 = $81.86.

Answer:

$72 per day at Busch garden

$92 per day at universal

Explanation:

let a = cost per day at Busch garden

   b = cost per day at Universal

The cost for 2 days at Busch garden and 3 days at universal is $420. The statement can be expressed as follows:

The sum can be expressed as

2a + 3b = 420........................(i)

The cost for 4 days at Busch garden and 2 days at universal is $472. It can be expressed as

4a + 2b = 472......................(ii)

The equation forms a simultaneous equation.

2a + 3b = 420........................(i)

4a + 2b = 472......................(ii)

from equation (i) make a subject of the formula

2a = 420 - 3b

divide both sides by 2

a = 420/2 - 3b/2

a = 210 - 3b/2

insert a in equation (ii)

4(210 - 3b/2) + 2b = 472

840 - 6b + 2b = 472

840 - 4b = 472

-4b = 472 - 840

-4b = -368

divide both sides by -4

b = -368/-4

b = 92

Insert b in equation (i)

2a + 3b = 420

2a + 3(92) = 420

2a + 276 = 420

2a = 420 - 276

2a = 144

divide both side by 2

a = 144/2

a = 72
