A recipe for crumb cake says to mix 3/8 cup of brown sugar and 1/3 cup of white sugar. From this sugar mixture, set aside 1/4 cu
ch4aika [34]

brown sugar= \frac{3}{8}

white sugar= \frac{1}{3}

you need to mix brown sugar with white sugar

\frac{3}{8} + \frac{1}{3} = \frac{9+8}{24} = \frac{17}{24}

then it says you need to set aside 1/4 for the crumb topping from the previous sugar mixture that was  \frac{17}{24}, so

\frac{17}{24} - \frac{1}{4} = \frac{68-24}{96} = \frac{11}{24}

The sugar mixture used to make the cake is \frac{11}{24}

MaRussiya [10]

The gym teacher has $250 to spend on volleyball equipment. She buys 4 volleyball nets for $28 each. Volleyballs cost $7 each. How many volley balls can she buy

Answer:

she can buy maximum of 19 balls.

Step-by-step explanation:

Let the number of volleyballs  be x

we know that

\text{(The cost of each volleyball net} \times \text{number of volleyball net)}+\text{(the cost of each volleyball} \times \text{number of volleyballs)}\leq \ 250

so substituting the values,

28(4) + 7x \leq 250

112 + 7x \leq 250

7x \leq 250 - 112

7x \leq 138

x \leq \frac{138}{7}

x \leq 19.7
