A- dot 1 . that’s the answer but it’s making me type 20 words.
It is 13.5 Simiply multiply nine times 1 1/2. An easier way to did this might be making one half into a decimal 1.5
For part A: the constant is 83.50. the variable would be c and w. and the coefficient would be 10c or 15w.
part B: so 10(4)+15(15)+83.50 -----> 10x4= 40------> 40+15(15)+83.50---->15x15=225
40+225+83.50=348.50
part C The coefficient would change because a constant is always constant, a variable is just a letter standing in for a number which would make the coefficient the one that changes for $10 to $20.
hope that help!
