Answer: Original salary = $500
Step-by-step explanation: Tricia got a 6% raise on her weekly salary. The
raise was $30 per week.
Let x be the original salary
x times the raise percentage = raise amount
6%= 6/100=0.06, raise amount = 30
Now we solve for x
Divide by 0.06 on both sides
Original salary = $500
75x + 90(15-x)=88(15)
75x+1350-90x = 1320
-15x + 1350 = 1320
-15x= -30
x=2
the amount of 75 octane is 2 gallons
the amount of 90 octane is 13 gallons
Hope this helps.
