Abat and a ball cost $1.10. the bat is $1 more than the ball. what does the ball cost?

1.05 is the answer
Write an algebraic equation to solve
a= ball
b= bat
a + b = 1.10
Write out the equation for the ball (a = b + 1)
substitute the equation for the ball into the original equation
(b + 1) + b = 1.10
simplify the equation
2b + 1 = 1.10
Solve the equation
2b + 1 = 1.10
-1. -1
——————-
2b .1
/2 /2 = .05

Plug in your answer into the equation for the ball (a= b + 1)
a= .05 + 1
1.05 is your answer

Ifound this on google “that means that the graph of a function with direct variation has these features: it is a straight line: because the slope is the ratio y/x = k. it passes through the origin (0,0): because y = kx = k (0) = 0.” i hope this you for what your looking for

It is 6% because if you subtract 69-58=6 so 6% is the answer to your question.
