Harlamova29_29 [7]
If Vicki works 19 hours per week att $17.30 per hour, then her weekly savings is (17.30)(19) = $328.70 So, if she needs to save at least 4 000, then she it will take her (4000/328.70) which is approximately 12.17 weeks. That means she has to save for at least 13<span> weeks. </span>
