Answer:
t = 0.06c
Step-by-step explanation:
Given the following :
Percentage sales tax on items = 6%
Cost of item = c
Amount of sales tax on item = t
Amount of sales tax is the product of the sales tax percentage and the cost of item purchased
Hence, Amount of sales tax;
t = 6% × cost of item (c)
t = 0.06 × c
t = 0.06c
Answer:
a = 3, b = -1
Step-by-step explanation:
a = 5b + 8
a = -10b - 7
5b + 8 = -10b - 7
Add 10b from both sides;
15b + 8 = -7
Subtract 8 from both sides;
15b = -15
Divide both sides by 15;
b = -1
Lets substitute b;
a = 5b + 8
a = 5(-1) + 8
a = -5 + 8
a = 3

Answer:
<em>Part A: </em>
<em>c = 1.15p</em>
<em>c(2) = $2.30</em>
<em>Part B: </em>
<em>c = 0.90p</em>
Part B:
Step-by-step explanation:
<u>Linear Models</u>
Candy's Sweets Company charges $1.15 per pound to ship candy. This represents a proportional relationship between the pounds of candy and the cost.
Part A: If each pound costs $1.15, then p pounds cost $1.15p. Then the equation of the cost c is:
c = 1.15p
The cost of shipping p=2 pounds of candy is:
c = 1.15*2 = 2.30
c = $2.30
Part B: When the company reduces the cost by $0.25 per pound, the new unit cost is $1.15 - $0.25 = $0.90 per pound.
The new equation to determine the total cost for p pounds of candy is:
c = 0.90p
