One year, the number of subscribers for newspapers a was 7,600, and the number of subscribers for newspapers b was 3/4 of the number of subscribers for newspapers a. the next year, the number of subscribers for newspapers b increased by 25%. find the total number of subscribers for newspapers b the next year.

I believe the answer is 7,600, because 1/4 is equal to 25%, so if the number of subscribers for newspapers B is 3/4 the amount of subscribers of newspapers A, that means newspapers B had 75% of the amount of subscribers newspapers A had. Then they gained 25% of the amount of subscribers newspapers A had, that means that now they have 100% of the amount of subscribers newspaper A had. So now they have 7,600 subscribers.

)=(3)(6x)+(3)(−9)+−8(distribute)

7x+8x+2=18x+−27+−8

(7x+8x)+(2)=(18x)+(−27+−8)(combine like terms)

15x+2=18x+−35

15x+2=18x−35

tep 2: subtract 18x from both sides.

15x+2−18x=18x−35−18x

−3x+2=−35

step 3: subtract 2 from both sides.

−3x+2−2=−35−2

−3x=−37

step 4: divide both sides by -3.
