Lily likes to collect records. Last year she had 10 records in her collection. Now she has 13 records. What is the percent increase of her collection?

30%

Step-by-step explanation:

We know if we put the number of records in the end ÷ the number of records previously, we can get the percentage change.

13/10 = 1.3

1.3 - 1 (Because we want to find the increase, not the amount of percentage this is to that)

0.3 = 3/10 = 30%

the answer is 1/4

step-by-step explanation:

let y equal to

the total fare and x is the mile of taxi ride. so the equation is

y = 0.55x + 1.75

since susie has

$10 to spend for a taxi cab, so he can have

10 = 0.55x +

1.75

x = 15 miles of

taxi ride

so the system of

inequality is

10 < 0.55x +

1.75

x > 2
