Andrew and molly each collect coins. andrew has 548 coins in his collection. the given expression represents the number of coins in mollys collection. 548 × 5/4 molly claims she has fewer then andrew

Molly is incorrect. If you multiply by a fraction where the numerator is greater than the denominator, the number will increase. Molly actually has 685 coins.

Molly is incorrect, she has 685 coins in her collection.

Step-by-step explanation:

When solving the number of coins molly has, simply solve the equation (multiply 548 by 5/4) and you should get an answer of 648.

$180.806

Step-by-step explanation:

The computation of the total amount paid for the trip is shown below;

As we know that

Simple interest = Principal × rate of interest × time period

= (67.70 + 62.34 + 45.50) × 12% × 3 months ÷ 12 months

= 5.2662

Now the amount is

= Principal + simple interest

= 175.54 + 5.2662

= $180.806
