Gym members are instructed to lift their legs at a 30° angle during leg lifts. One member has legs that are 33 inches long. What is the height (in inches) of the member’s feet during the leg lift? If necessary, round decimal answers to the nearest tenth.

answer: the answer is b. i think hope i got it correct

step-by-step explanation:

$25 becasue a 10 increase would make it from 80 to 50

the answer is $4.45. i started by figuring out the cost of the plates and napkins. the easiest way to figure this cost out is through the tax. we know the way they found the tax is by multiplying the cost of non-food items by the tax rate (5% or 0.5). so, all we have to do to find the cost before tax is set up an equation and work this formula backwards. the equation is 0.19=0.05x where x is the cost of the plates and napkins. now all you do is divide both sides by 0.05 to come up with 3.8=x. now that we know the cost of the plates and napkins is $3.80, all we have to do is subtract this cost from the total cost of $8.25 giving us the cost of the watermelon which is $4.45.
