A candy bar and a piece of bubble gum together cost 1.50. The candy bar costs a dollar more than the bubble gum. How much does the piece of bubble gum cost, in cents?
+10 It is a little tricky, but the bubble gum is 25 cents, that is because 25 cents plus 1 dollar 25 cents is 1.50. So you have it \(25\)
Andy is correct. Good work.
Here's the calculation your teacher wants to see.
A candy bar and a piece of bubble gum together cost 1.50.
The candy bar costs a dollar more than the bubble gum.
How much does the piece of bubble gum cost, in cents?
Call the cost of a candy bar "C"
Call the cost of a bubble gum "B"
C + B = 1.50
C – B = 1.00
Just subtract the second from the first 2B = 0.50
B = 0.25 = 25¢
