In this question, we're trying to find how many science kits Ms. Clark bought.

We know that she spent a grand total of $89.85 on the science kits, this price also includes the tax she paid.

We know that she payed $4.85 in taxes

We also know that each kit cost $5 each

Lets first get rid of the tax in the final price.

89.85 - 4.85 = 85

Without tax, she spent $85

Since we know that each kit costs $5 each, we would divide 85 by 5 to see how many kits she bought.

85 ÷ 5 = 17

This means that she bought 17 science kits.

17 science kits

step-by-step explanation:

we can use this expression to calculate the energy gain as a particle moves with a field or the energy loss as it moves against it. (note that it is also used to define the electron-volt, a unit of energy equal to that gained by an electron as it falls through a pd of 1 v, i.e. w = 1 ev = 1.6 10-19 c 1 v = 1.6 10-19j).in fact this expression is really nothing more than the statement that potential is the potential energy per unit charge. in this case, v= w/qis simply stating that the change in potential energy(or work done) per unit charge is equal to the change in potential (or potential difference), v.student questions: uniform electric fields2electron beamcathode+5 kvanode0 v

$54.99

step-by-step explanation:

$54.99 includes 500 min. if she does not exceed 500 min then her bill is $54.99
