With tax, it would be 107.5% of 625.99. 107.5% is 1.075 in decimal form so you do 1.075(625.99). That gives the rounded answer of $672.94. :)
V1=60. 60×t1=50×t2=S
V2=50
T=t1+t2=5. 5-t2=t1
60×(5-t2)=50×t2
300-60×t2=50×t2
300=50×t2+60×t2
300=t2×(50+60)
300=t2×110
300/110=t2
S=50×300/110
Answer:
150 + 150 = 300
Step-by-step explanation:
50x = 30y
x + y = 8
~~~~~~~~~~~~~~~
x = 8 - y
50(8-y) = 30y
400 - 50y = 30y
400 = 80y
y = 5
x= 3
