The amount of money that is left in a medical savings account is expressed by the equation y = -24x+ 379, where x represents the number of weeks and y represents the amount of money, in dollars, that is left in the account. after how many weeks will the account have $67 left in it?

y = amount left so y = 67

rewrite the equation as:

67 = -24x+379

subtract 379 from both sides

-312 = -24x

 divide both sides by -24

x = -312 / -24

x = 13

the answer is 13 weeks

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40
