linear model

Step-by-step explanation:

We can write our linear model like this: y = . 082x, where y is the cost of the bill, and x is the amount of electricity used. You can use slope-intercept form, which is y = mx + b, to write equations for linear models. m is the slope or rate-of-change, and b is the y-intercept.

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.

then,

we have an inequality i.,e

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

the answer is 24
