Which expression gives the best estimate of 45 percent of 76? 1/4(80) 1/5(80) 1/2(80) 1/9(80)

1/5(80)

Step-by-step explanation:

Well, 45% of 76 is 34.2

Which can be solved by converting 45% to .45 and then multiplied by 76

1/4(80) can be converted into .25*80 which is 20

1/5(80) can be converted into .20*80 which is 16

1/2(80) can be converted into .50*80 which is 40

1/9(80) can be converted into .11*80 which is 8.88

The closest one is 1/5(80) which solves the estimate,

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

what is the answer?
