Answer:
900 batteries
Step-by-step explanation:
First we must find how many batteries does 1 calculator need
we can do this by dividing 160 by 40
which will give us 4 batteries per calculator
then we multiply the amount of calculators we have with 4
225×4 = 900 so we need 900 batteries
It depends on the variable.
If it's something like x < 2, your graph would be a vertical line at x = 2, and everything to left of that line shaded in (because of the less than).
Similarly for y, except it would be a horizontal line with either everything above or below shaded.
You can have other equations like 0<x<4 where everything between x = 0 and x = 4 would be shaded
I believe a would be on the first line.

Step-by-step explanation:
Answer: the actual amount that Luke paid including tax is $55.65
Step-by-step explanation:
The initial price of the jacket is $75.
Luke bought a jacket that was 30% off the cost. This means that the amount of discount on the Jacket is
30/100 × 75 = 0.3 × 75 = $22.5
The price of the jacket after the discount had been applied is
75 - 22.5 = $52.5
He paid sales tax of 6% after the discount had been applied. This means that the amount of sales tax that he paid on the jacket is
6/100 × 52.5 = 0.06 × 52.5 = 3.15
Therefore, the actual amount that Luke paid including tax is
52.5 + 3.15 = $55.65
