Answer:
a) 36
b) 11:5
Step-by-step explanation;
a) let the number of cold stone cones be x
Since the initial ratio is 11:9
we have the ratio of the ice creams as;
11:9 = 44:x
11/9 = 44/x
11 * x = 9 * 44
x = (9 * 44)/11
x = 9 * 4 = 36
b) Now, from 36, we have a number of cold stones as 20
So the ratio now will be;
44:20
and that would be;
11:5
Answer: 26
Step-by-step explanation:
Answer:
y = 7x
y = $133
Step-by-step explanation:
x = independent variable
y = dependent variable
y = 7x
Where,
y = total amount saved
x = number of weeks
7 = constant
When x = 19
y = 7x
y = 7 * 19
y = 133
y = $133
