Answer:

A) R = P/I²

Step-by-step explanation:

I = √P/R

Square each side

I^2 = (√P/R)^2

I^2 = P/R

Multiply each side by R

I^2R =P/R * R

I^2R = P

Divide by I^2

I^2R / I^2 = P/ I^2

R = P/ I^2

h and p are the number of history and psych textbooks, respectively.

store sold a total of 411 textbooks in a week.

h + p = 411

The number of history textbooks sold was 69 less than the number of psychology textbooks sold.

h = p - 69

Substitution

(p-69) + p = 411

2p = 411+69

p = 240

h = p-69 = 171

171 history books and 250 psych books
