sealake101 · Answer

so you aren't adding you will be subtracting so that leaves you with choices c and d

anonymous202 · Answer

yes I think it might be c because if she is buying 3 Barretts the B will go by the price but I'm not so sure

sealake101 · Answer

not C but its D, you want to make sure you add the variable to 3, so it would be 35.79 minus 3 b
