Your class is raising money for a class trip. you make $10 on each pizza and $4 on each box of cookies that you sell.
how many items of each type must you sell to raise more than $100? write and graph an inequality to model the
situation. define the variables and state the constraints. give three possible combinations that you could sell.
p = 8h
calculating the hourly rate of pay from the amount paid for hours worked.
thus the hourly rate is $8 per hour
let p be the amount paid and h the hours worked then the rule is
p = 8h

left point: a=x=0
right point: b=x=10
width of each of the five equal intervals: w=r/5→w=10/5→w=2
the first midpoint is x1=a+w/2→x1=0+2/2→x1=0+1→x1=1
the second midpoint is x2=x1+w→x2=1+2→x2=3
the third midpoint is x3=x2+w→x3=3+2→x3=5
the fourth midpoint is x4=x3+w→x4=5+2→x4=7
the fifth midpoind is x5=x4+w→x5=7+2→x5=9
there are several ways to go at this. here's one of them.
multiply the second equation by 9/9, then substitute for 9y from the first equation.
(9y)/(9z) = 7/5
(7x)/(9z) = 7/5
now, multiply by 9/7.
x/z = (9/7)(7/5) = (9·7)/(5·7)
x/z = 9/5
it is negative periodic rational number
it is a negative periodic rational number with period 07 that can be written differently:
- 9. = - 9,(07)
