The range is all real numbers.
The function given simplifies to just f(x) = 4x.
This is just a straight line that is increasing from left to right. If we reflect the line over the x-axis, it is still a line that goes on forever in each direction.
Therefore, the range will be all real numbers.
171.76 ÷ 555 = 0.3094774775
Answer:
$13.60
Step-by-step explanation:
First let's find how much Gerry spends on lunch in 2 weeks (assuming she goes to school 5 days a week):
$1.25*10=$12.50
Now we find out how much she pays for the extra snack. Since in 2 weeks there are 2 Fridays then:
0.55*2=$1.10
Then we add these two together to get:
$12.50+$1.10=$13.60
