Answer 3

for part a on 1 I got 257=2.25x+1.50x=463.50 does that look right?

Answer 4

Convert dollars to cents so that the numbers are integers.
Solve the following simultaneous equations derived from the problem statement:
{ 225p+150d=46350, p+d=257 }

Answer 5

would I divide 46350 and 257 to solve

Answer 6

Multiply both sides of the second equation by 150 and then subtract the 2nd
equation from the 1st. The d terms should subtract out.
Then solve what is left for p.

Answer 7

d=153 p=104
