Lila decided to make more baked goods for the bake sale she used 1/8 lb less flour to make the bread then to make the cookies. she used 1/4 pound more flour to make cookies than to make brownies. if she used a half pound of flour to make bread how much flour did she use to make brownies

The total lb flour is used to make brownies.

Step-by-step explanation:

Let x lb flour is used to make brownies.

She used 1/4 pound more flour to make cookies than to make brownies. So, the total flour is used to make cookies is

she used 1/8 lb less flour to make the bread then to make the cookies. So, the total flour is used to make bread is

It is given that she used a half pound of flour to make bread.

Therefore total lb flour is used to make brownies.

7.1

Step-by-step explanation:

Exponential Functions:

y=ab^x

y=ab  

x

a=\text{starting value = }570

a=starting value = 570

r=\text{rate = }26.9\% = 0.269

r=rate = 26.9%=0.269

\text{Exponential Decay:}

Exponential Decay:

b=1-r=1-0.269=0.731

b=1−r=1−0.269=0.731

\text{Write Exponential Function:}

Write Exponential Function:

y=570(0.731)^x

y=570(0.731)  

x

Put it all together

\text{Plug in time for x:}

Plug in time for x:

y=570(0.731)^{14}

y=570(0.731)  

14

y= 7.091174

y=7.091174

Evaluate

y\approx 7.1

y≈7.1
