Craig has a twenty dollar bill. he buys six squirt guns for$2 each. how much money did craig have left?

I believe he had $8 left.

You just have to set up an equation and plug in the numbers and then solve like so- 

20 - 2x
20 - 2(6) 
20 - 12 
8

Craig has $8 left. Hope this helped, plz mark brainliest : ) 

1.   an exact solution requires a radical solution - no decimal approximation.2. (a)4x^3 = 756x^3 = 756/4 = 189x =   cube root of 189 =   5.74   to nearest hundredth answer(b)   189 = 3*3*3*7   so we can write the cube root of 189 as 3∛7 answerchecking (a) 4*(5.74^3 =   756.48   which is very close(b)   4* ((3∛3)^3   = 4*189   = 756   - spot on! 3. i would use solution b because the original question asked for an exact solution.
