you move first the number without the variable to the other side with the opposite sign
-0.75p=0.25+2
-0.75p=2.25
then as -0.75 is multiplying you pass it to the other side dividing
p=2.25/-0.75
p=-3
Answer:
Step-by-step explanation:
Mp=$1200
Let sp be x
SP=MP-discount% of MP
x=1200-15/100 * 1200
x=120000-18000/100
x=102000/100
x=1020
the amount of money person saves=MP-SP
=$1200-$1020
=$180
therefore he saves $180
