Answer: first one
Step-by-step explanation:
Answer:
$0.65
Step-by-step explanation:
x=cost of washcloth
x+1.20=cost of towel
Now,
x+x+1.20=2.50
2x=1.30
x=0.65
So, cost of washcloth is $0.65
162 is the anwser.Hope i helped.
Solve for x then replace x with f⁻¹(x) and y with x
y=(4^x-5)/3
times 3
3y=(4^x-5)
add 5
3y+5=4^x
take log₄ both sides
log₄(3y+5)=x
switch
f⁻¹(x)=log₄(3y+5)
(10,84)(20,159)
slope(m) = (159 - 84) / (20 - 10) = 75/10 = 7.5
y = mx + b
slope(m) = 7.5
use either of ur points...(10,84)...x = 10 and y = 84
now we sub and solve for b, the y int
84 = 7.5(10) + b
84 = 75 + b
84 - 75 = b
9 = b
so ur equation is : y = 7.5x + 9...with each shirt costing $ 7.50 and the one-time set up fee costing $ 9.00...with y being the total cost and x being the number of shirts bought
for 30 shirts......x = 30
y = 7.5(30) + 9
y = 225 + 9
y = 234 <== cost of an order of 30 shirts
