Ok so what you fo to solve this is you take .26 and .70 and multiply them. to get 0.183 and then multiply it by 41 which equals 7.462 you then subtract it and get 33.54% still an F
here is the problem I used for the equation to solve this.
(.26×.70)×41-41= -X
you do order of operations P) parrenthises E) exponents M) multiplication D) division A) Add S)Subtract
