Answer: the right cost is $1.05 for a bat and 0.5c for a ball.
Step-by-step explanation:
Let's imagine x in the price of bat and y is the price of the ball
From the infor we know that:
x + y= 1.10 (dollars)
and since the bat is $1 more than the ball we can ensure that:
x - 1 = y
Now we can replace y as follow:
x + x - 1 = 1.10
2x - 1 = 1.10
2x = 1.10 + 1
2x = 2.10
x= 2.10/2= 1.05 (dollars)
Answer:
x=-82
subtract 74 from -130 and then divide -164 by two
