Answer 1

Answer:

Step-by-step explanation:

You want to start by subtracting 2.10 - 2 which = $0.10

Answer 2

The cost of the tennis ball is $0.05.

• Let the cost of tennis racket be R.

• Let the cost of tennis ball be B.

To find the cost of the tennis ball:

Translating the word problem into an algebraic expression, we have;

$R + B = 2.10$   ....equation 1

$R = B + 2$    .....equation 2

Substituting eqn 2 into eqn 1, we have;

$B + 2 + B = 2.10\\\\2B + 2 = 2.10\\\\2B = 2.10 - 2\\\\2B = 0.10\\\\B = \frac{0.10}{2}$

Tennis ball, B = $0.05

Therefore, the tennis ball cost $0.05.
