5.
In a bag of 53 cherry- and watermelon-flavored candies, there are 19 more watermelon than cherry candies. Write an equation to determine how many candies are cherry.
A.
If
c
= number of cherry candies,
c
+ 19 = 53.
B.
If
c
= number of cherry candies,
c
+ (
c
+ 19) = 53.
C.
If
w
= number of watermelon candies,
w
+ (
w
+ 19) = 53.
D.
If
w
= number of watermelon candies,
w
+ 19 = 53.
