Q:
Please solve the following problem!!A bat and one ball cost one dollar and ten cents. The bat costs one dollar more than the ball. How much does the ball cost?Inappropriate answers will be reported!!
Accepted Solution
A:
1 bat & 1 ball costs $1.10
bat = a
ball = b
a = b + 1
a + b = 1.10
plug in b + 1 for a
(b + 1) + b = 1.10
Simplify
b + b + 1 = 1.10
2b + 1 = 1.10
isolate the b
subtract 1 from both sides
2b + 1 (-1) = 1.10 (-1)
2b = 0.10
divide 2 from both sides
2b/2 = 0.10/2
b = 0.10/2
b = 0.05
Plug in 0.05 for b into one of the equations
a = b + 1
a = 0.05 + 1
a = 1.05
bat = $1.05
ball = $0.05
hope this helps
