Tiya earns $7 an hour mowing her neighbor's lawn. create two variables and determine which is dependent and which is independent for this situation.

70

step-by-step explanation:

2*5=10

4*15=60

60+10=

70

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt
