Elsa's grandmother paid her x dollars a week to mow the lawn during the summer. elsa decided to save some of her money and spend the rest. for the first 4 weeks, elsa put $10 per week into savings. for the next 8 weeks, she put $15 per week into savings.
pick all the expressions that represent how much money elsa spent.

4(x–10)+8(x–15)

(4x+8x)–(40+120)

12x–160

(4x–40)+(8x–120)

Amount of money Elsa spent= amount of money given by grandmother,x - amount of money saved.

Hence for the first four weeks, amount spent= 4(x-10) as she saved 10 per week for 4 weeks.

For the next eight weeks, amount spent= 8(x-15) as she saved 15 per week for 8 weeks.

Thus the answer would be the first option.

.

step-by-step explanation:

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
