Some high school students want to collect eight million pennies for charity. How many dollars is that?
+2446 \($80000\)
This problem is fairly simple, actually. You can set up a proportion. As a reference, 100 pennies is the equivalent of one dollar:
\(\frac{100pennies}{$1}=\frac{8000000pennies}{$x}\)
Cross multiply to solve the proportion:
\(100x=8000000\)
Finally, divide by 100 on both sides to isolate x:
\(x=$80000\) And of course, leave the units in your final answer!
