Question

17. Carol and Cathy are each saving money for a vacation. Carol started with $25 and saves
$7.50 a week. Cathy started with $10 and saves $10 a week. When will they have saved
the same amount?

Answer 1

Answer:

6 weeks

Step-by-step explanation:

Let x represent the weeks

$25=10+ (10x-7.5x = 2.5)$

$25-10=2.5x = 15$

$\frac{15}{2.5}=x \\(150/25)\\x=6$
