Answer:
They must work for more than 4 hours for Tom's bonus to be greater than Sara's
Step-by-step explanation:
Tom pay: 12.75x+25
Sara pay: 11.75x+29
Tom>Sara = 12.75x+25>11.75x+29
subtract 25 both sides
12.75x>11.75x+4
subtract 11.75x both sides
x>4
Answer: 45
Step-by-step explanation:
The store has to sell
45
pairs of shoes.
Explanation:
The store has a base cost of
$
1800
, the cost per pair of shoes is
$
25
. Each pair of shoes is sold for
$
65
, therefore the profit per pair of shoes is
$
65
−
$
25
=
$
40
The formula for calculating the amount that needs to be sold would look like this;
40
x
=
1800
To determine the value of
x
, we take this formula;
x
=
1800
40
x
=
45
Therefore, the store needs to sell
45
pairs of shoes to break even.
The radius of the circle would be 12
