300*5= 1500
1500/450= 3.3333
3.3333*$2.00= 6.6666
Answer= $6.67
Solve each
5x+7>-8
minus 7 both sides
5x>-15
divide by 5
x>-3
3x+7≤19
minus 7 both sides
3x≤12
divide by 3
x≤4
so we got
x>-3 AND x≤4
and means that the solution set must satisfy both at once
so x is bigger than -3 and less than or equal to 4
so between -3 and 4 including 4
-3<x≤4
last one
Answer: 350
Explanation:
a = adult tickets
s = student tickets
║ a + s = 754
║s = a + 54
Plug s = a + 54 into a + s = 754
a + (a + 54) = 754
a + a + 54 = 754
2a + 54 = 754
2a = 754 - 54
2a = 700
a = 350
Answer:
Range
The set of output values is called the range of the function.
c (cost)
m (month)
c= xm + b
$424.20= 24.95m+ $49.95
Move everything except variable on one side.
424.20 - 49.95 = $374.24
$374.25 = 24.95m
Divide by 24.95
m = 15
15 Months
