+10 The supply store sells 4 pencils for every 5 pens. The store sold 28 pencils yesterday. How many pens did the store sell?
+177 The given information states that 4 pencils is sold for every 5 pens. This information can be represented mathematically as a ratio \(\frac{4 \text{ pencils}}{5 \text{ pens}}\). We know that the store sold 28 pencils yesterday. We can set up a proportion and solve to determine the number of pens sold.
\(\frac{4\text{ pencils}}{5\text{ pens}} = \frac{28\text{ pencils}}{p \text{ pens}} \\ 4p = 28 * 5 \\ p = \frac{28 * 5}{4} \\ p = 7 * 5 \\ p = 35 \text{ pens}\)
+121 Let's use the given information to solve this problem. We know that the ratio of pencils to pens sold is 4:5. This means that for every 4 pencils sold, 5 pens are sold.
If the store sold 28 pencils, we can set up a proportion:
Pencils sold / Pens sold = Ratio of pencils to pens
Substituting the values:
28 pencils / Pens sold = 4 pencils / 5 pens
Now, solve for the number of pens sold:
Pens sold = (28 pencils * 4 pens) / 4 pencils
Pens sold = 33 pens
Therefore, the store sold 33 pens.
