Cycle Shop raises the price of a bicycle to 225% of what it paid to its supplier. Bike Rack raises its retail price to 150% of what it paid to its supplier. But the two prices
ended up the same. What could have been the prices the stores paid to their
suppliers?

after simplifying it i got: -36.25 as my answer. hope that !

step-by-step explanation:

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

the eight graders whould be the answer
