Answer:
B. 225 - 45 = 10d
Step-by-step explanation:
The remainder Ezra needs to save can be earned by walking ten dogs.
Let remainder = r
Let dogs = d
This means:
r = 10d
Make 'r' numerical values.
r = Total cost of snowboard - Current savings
r = $225 - $45
Therefore:
225 - 45 = 10d
The equations that can be solved to find how much Ezra is paid for walking each dog is B. 225 - 45 = 10d.
The subject in an equation is the/a variable(s) we're solving the equation for.
Usually, we want it to stay separated and clean without mixing with other constants or variables so that its value is clearly visible.
Ezra is saving money to buy a snowboard that costs $225.
He already has $45 and can earn the rest by walking ten dogs.
If d represents how much he earns for walking each dog,
Let r be the remainder that needs to save can be earned by walking ten dogs.
So,
r = 10d
Make 'r' numerical values.
r = Total cost of snowboard - Current savings
r = $225 - $45
Therefore,
225 - 45 = 10d
