If 750 is 30% of y, what is 70% of y?

A)525 B)1500 C)1575 D)1750 E)2500

D. 1750

Step-by-step explanation:

750 = 30% then 1% = 750/30 which is 25

70% you multiply what 1% is by 70, which is 25x70 = 1750

Step 1:

30/100 x Y = 750

Y = 750 x 100/30

Y = 2500

Step 2

X = 70%Y

X = 70/100 x 2500

X = 1750

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.

is only a line? i think so
