A recipe calls for 3-4 cup of rice. how much rice is needed to triple the recipe.​

$831.60

Step-by-step explanation:

Assuming that 0.16 is a percent:

Recall that the simple interest formula is a=p(1+rt).

a= final amount (Unknown)

p=starting amount ($770)

r= interest rate (0.16%)

t=time in years (6 months = 0.5 years)

Plug numbers into formula:

a=770(1+0.5*0.16)

Solve parentheses according to PEMDAS:

a=770(1.08)

Multiply:

a=831.6

$831.60
