Question

4. Tolani has a coin jar containing n nickels and d dimes worth a total of$3.65. The equation 0.05n + 0.1d = 3.65 is one way to represent thissituation. Which equation is equivalent to the equation 0.05n +0.10 + 3.65?O Sn + d = 3650 0 5n + d = 365Osn - 100 = 3650 050 016 = 365

Answer 1

In order to find an equivalent equation, we multiply the equation by the same factor on both sides, in this case 3.65 is being multiplied by 100 to become 365.

This means that the equation equivalent should be like this

`100\cdot(0.05n+0.1d)=100\cdot3.65`

then we simplify both sides of the equation

`5n+10d=365`
