Answer:
£20
Step-by-step explanation:
1-1/4=3/4
3/4=15
1
1*15/3/4
15*4/3=20
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!
4x - 12
You can get this by switch the f(x) and the x and then solving for the new f(x)
