Question

Patrician saves $ 1.20 everyday while her sister Nicole saves $ 2.80 daily. The two girls saved $ 150.00 together. How much of this amount was saved by Nicole?

Answer 1

Amount saved by Nicole is $ 105

Solution:

Given that Patrician saves $ 1.20 everyday and Nicole saves $ 2.80 daily

The two girls saved $ 150.00 together

To find: Amount saved by Nicole

Let "x" be the number of days for which Patrician and Nicole saved money

Given that they both saved $ 150.00 together

So we can frame a equation as:

$\text{(amount saved by patrician + amount saved by nicole) } \times x = 150.00$

$(1.20 + 2.80) \times x = 150\\\\4x = 150\\\\x = 37.5$

Therefore amount saved by nicole:

Nicole has saved $ 2.80 daily for "x" days

$\text{ Amount saved by Nicole } = x \times 2.80\\\\\text{ Amount saved by Nicole } = 37.5 \times 2.80 = 105$

Thus amount saved by Nicole is $ 105
