Matthew has $50 in his saving, and his saving = y, y = 50
He spends $4 (the m) on snacks each time
50 = 4x + 8
Isolate the x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
First, subtract 8 from both sides
50 (-8) = 4x + 8 (-8)
42 = 4x
Divide 4 from both sides
(42)/4 = (4x)/4
x = (42)/4
x = 10.5
John Matthew buys 10 snacks (since he cannot buy 1/2 a snack)

Answer:
x=3.75
Step-by-step explanation:
15x - 45= 3x
Subtract 15x from both sides:
-45 = -12x
Divide both sides by -12, the -12's cancel and you get:
-45/-12 = 3.75
x= 3.75

Answer:
No maximum
Step-by-step explanation:
Given
Solving (a): The minimum
The minimum is when the absolute parameter gives 0
i.e.
Divide both sides by 0.9
Open bracket
Remove absolute sign
Collect like terms
Then the y value is:
Recall that:
So, we have:
Hence, the minimum is at: 
Since the minimum is at , then the graph will open upwards.
Hence. the function has no maximum; i.e.
2. 16100 grams
3. 3.0473 kilos
