Question

anonymous · Answer

lets call "x" to the number of candy bars Sarah can eat and "y" to the amount the dog can eat, our first equation would be:
"The number of candy bars Sarah can eat is 3 times the amount her dog can eat"
translate it to X and y language:
"X is 3 times Y"
and to equations:
$$x=3y$$
it is your turn to write the second one:
"Sarah and her dog ate a total of 40 bars"
