87. Juanita started with 40 dollars in her pocket.
Then she bought one CD for 7.99 dollars and 1 DVD for 8.99 dollars.
It has a sales tax of 7% on these items.
Plus she bought a lunch for 4.25 dollars including tax
Solve:
=> 7.99 dollars + 8.99 dollars = 16.98 dollars
=> 16.98 dollars * .07 = 1.2 dollars
=> 16.98 + 1.2 = 18.18 dollars
Plus the lunch
=> 18.18 + 4.25 = 22.43 dollars
=> 40 – 22.43 = 17.57 dollars
Answer:
Gale's Shipping Company Cost, y=$(3+5x)
Peeta's Shipping Cost, y=$(12+2x)
Step-by-step explanation:
Let the number of pounds being shipped=x
Gale's Shipping Company charges $3.00 plus an additional $5.00 per pound to ship a package.
Gale's Shipping Company Cost = $3.00 + ($5.00 X Number of Pounds)
Gale's Shipping Company Cost, y=$(3+5x)
Peeta's Shipping Company charges $12.00 plus an additional $2.00 per pound to ship a package.
Peeta's Shipping Cost = $12.00 + ($2.00 X Number of Pounds)
Peeta's Shipping Cost, y=$(12+2x)
Step-by-step explanation:
Volume =pir^h
V1=pi r1^h
V2=pir2^2h
Now,V1/V2=r1^2/r2^2
v1/v2=r1^2/(1.05)^2 ((r2=r1+5/100r1)
v1/v2=1/1.1025
v1/v2=0.907
(v1/v2-1)=0.0907×100%
(v1-v2)/v2=9.07%
increase in volume is 9.07%
