Tina pet sits to earn extra money. she charges a flat service fee of $20, plus $20 per day. if one of her customers spent less than $80, which of the following inequalities could be used to solve for x, the number of days the customer paid for pet sitting? a) $20x + $20 < $80b) $20x < $80c) $20x - $20 < $80d) $20x < $100

option A is the correct answer.

Step-by-step explanation:

Let x represent the number of days the customer paid for pet sitting.

She charges a flat service fee of $20, plus $20 per day. This means that the total amount that she charges for x hours would be

20 + 20x

If one of her customers spent less than $80, then the inequality that could be used to solve for x would be

$20 + $20x < $80

step-by-step explanation:

use pothagarean therom

a^2+b^2=c^2 so first ac

acm is a right triangle because c= 90°

and am (the hypotenuse or c) =16+9 =25

but there is not enough info we need another angle or side length

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.
