Answer:
a₁ = 37
Step-by-step explanation:
In an arithmetic progression the common difference d is
d = a₂ - a₁ = a₃ - a₂ , that is
2x - 18 - (x + 1) = 2x - 1 - (2x - 18) ← distribute and simplify both sides
2x - 18 - x - 1 = 2x - 1 - 2x + 18
x - 19 = 17 ( add 19 to both sides )
x = 36
Thus
a₁ = x + 1 = 36 + 1 = 37
Answer:
The price of one hot dog is $1.65
Step-by-step explanation:
8h+4c= x
c= 1.25
x= 18.20
8h + 4(1.25)= 18.20
8h + 5 = 18.20
( subtract 5 from both sides of the equation)
8h = 13.20
( divide both sides by 8 to isolate the variable)
h = 1.65
so each hot dog is 1.65
Answer: $61.48
Step-by-step explanation:
First, let’s find her cost before tax by adding everything she bought together.
50+5+3=58
Then, find the cost of sales tax.
Convert 6% to a decimal
6/100=0.06
Multiply the total cost by the decimal
58*0.06=3.48
Add the tax and total cost together
58+3.48=61.48
So the total cost with tax is $61.48
