Solve for n. 13n + 85 = 176

n=7

Step-by-step explanation:

13n+85=176

*Subtract 85 from both sides

13n+85-85=176-85

*Simplify

13n=91

*Divide both sides by 13

13n=91

13    13

*Simplify

n=7

Hope this helped :)

341

step-by-step explanation:

all you have to do is 9x31 (which equals 279) and then 20x31 (which equals 620). then you have to subtract. 620-279=341.

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

subtract 112.49 from both sides we get;

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