Answer:
2 should be distributed as 2y + 8; y = 4
Step-by-step explanation:
2(y + 4) = 4y
Distribute
2y + 8 = 4y
Step 2 is incorrect because the added instead of multiplied
Continuing on to correct the problem
Subtract 2y from each side
2y+8-2y = 4y-2y
8 = 2y
Divide by 2
8/2 = 2y/2
4 =y
I would say your friends assumption is wrong. Why?
Because, if you payed $2.40 for 3/4 pounds of grapes, your friend should pay more for an entire pound, not less.
Hope this helped! c:
40 is 20% of x
40 = .2 * x
40/.2 = x
x =200
x is 80% of y
x = .8 * y
200 = .8 *y
200/.8 = y
250 =y
x+y
200+250
450
