To find the LCD first convert all integers and mixed numbers (mixed fractions) into fractions. Then find the least common multiple ( LCM ) of the denominators which is equal to the least common denominator ( LCD ). You can then rewrite each term as an equivalent fraction with the LCD .
Answer: It will take her more than 9 weeks.
Step-by-step explanation:
If she already has $150 that will be constant and if she can save $45 per week the we will have the expression 45w where w is the number of weeks.
Together it will be 150 + 45w
Now the money has to be at least $560 so it will be
150 + 45w ≥ 560 Now solve for w
-150 -150
45w ≥ 410
w ≥ 9.1
Which means it will take 10 or more weeks t
