Kerry charges $22.50 per lawn to cut grass on Saturdays and $18.50 per lawn to cut grass on Sundays. If she cuts 4 lawns on Saturday and 5 on Sunday, how much money will she earn?

$182.50

Step-by-step explanation:

22.50x4=90

18.50x5=92.5

90+92.5= $182.50

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.

120 seems like the most sensible answer.

step-by-step explanation:

if there is only one topping on all caramel apples and there's 120 of them. then all apples should/will be covered in sprinkles. make sense?
