If Jacob complaints 4/8 his homework Jessica completed and 8/10 of her homework Katie complete 12/15 of her homework did they complete the same amount prove if these fractions are equivalent using area models and number sentences.

no

Step-by-step explanation:

if Jacob completes 4/8 then he finishes 0.5 half for the homework

if Jess completes 8/10 then he finishes 0.8 'the for the homework

if Katie completes 12/15 then he finishes 0.8 'the for the homework

thus can be concluded Jess and Katie completed same amount of their homework - 80% of the total homework, but Jacob completed only half of his homework - 50%.

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
