A_n= a₁+(n-1)d
a₁ first term
n terms
d distance between each value
a_n= 12+(405-1)(5)=2032
Answer:
9 tshirts
Step-by-step explanation:
Money he had for t shirts= $75
Cost of shipping= $3
Money left for t shirts= $75-$3=$72
Cost of 1 t shirt= $8
We can find the answer with two ways:
1st way: tshirts of $8=1
tshirts of $72=72/8
=$9
2nd way: Cost ($) 8 72
T shirts 1 x
8/1=72/x
by cross multiply
x=72/8
x=9
If you would like to find the function that gives the profit Betty makes by selling a number of glasses of lemonade, you can find this using the following steps:
p ... profit
g ... glasses of lemonade
f(g) = p = g * $1 - $50
The correct result would be f(g)<span> = g * $1 - $50.</span>
Sine 35 degrees = x / 20
x = sine 35 degrees * 20
x = .57358 * 20
x = 11.4716
