y varies directly with x. y is 84 when x is 16. What is the constant of proportionality? (Write answer as improper fraction...Remember to reduce!)

5 1/4

Step-by-step explanation:

We use the formula for direct proportion to solve the question since we are informed that y varies directly with x and that y is 84 when x is 16.

The formula will be:

y = kx

where,

y = 84

x = 16

We then slot the values into the formula

y = kx

84 = 16k

k = 84/16

k = 5 1/4

The constant of proportionality is 5 1/4

3/10 times, the 5 year old will get a tablet. 5/10 times, the 13 yer old will get a tablet. multiply both fractions to get 15/100 times, both would have a tablet.
