While baking, Hannah discovered a recipe for cookies that required 3⁄4 cups of sugar for every 2 1⁄4 cups of flour. How many cups of sugar will she need for 4 cups of flour? (What if it was 1 cup sugar for every 3 cups of flour?)

1.3 cups

Step-by-step explanation:

if 3/4 cups of sugar are needed for every 2 1/4 cups of flour then for 4 cups of flour: (3/4*4)/(9/4) =1.3 cups of sugar

if 1 cup of sugar for every 3 cups of flour then

x=4/3=1.3

y = 0.77(x)

step-by-step explanation:

the jacket retains this value after 23% cut or retains 77% of original value. plug original 87 jacket price for x and the remaining value should be y.
