<span>This is not really a maths question, but rather a question about geography and climate: Sahara is a very dry place without any resources that gets very hot, especially during the day. If you camp on Sahara, you will not be able to find food or water, and you will be struggling with hiding from the heat. This would be very dangerous and you could potentially die - so you should not attempt to camp on the Sahara desert. </span>

Answer:
y = 3
+ 4
Step-by-step explanation:
Create 2 equations using values from the table to find a and b.
Using (0, 10), then
10 = acos0° + b ( cos0° = 1 ), thus
a + b = 10 → (1)
Using (90, 4), then
4 = acos90° + b ( cos90° = 0 ), thus
b = 4
Substitute b = 4 into (1)
a + 4 = 10 ( subtract 4 from both sides )
a = 6
Thus
y = 6cosx° + 4
When x = 45°, then
y = 6cos45° + 4 = 6 × 
+ 4 = 3 + 4
Let's make
A = adult tickets sold
C = child tickets sold
A + C = 162
5.90C + 9.50A = 1182.60
if .. A+C = 162 then A = 162 - C
substitute (162 - C) for A in the other equation.
5.9C + 9.5(162-C) = 1182.6
5.9C + 1539 - 9.5C = 1182.6
-3.6C + 1539 = 1182.6
-3.6C = 1182.6 - 1539
-3.6C = -356.4
C = -356.4/-3.6
C = 99 tickets
