Answer:

$3.90

Step-by-step explanation:

Cost per dollar = 5 cents

100 cents = $1

5 cents = 5/100

= $0.05

Number of cans = 78

How much money did she collect altogether?

Total money collected altogether = cost per cans × number of cans

= $0.05 × 78

= $3.90

The answer is $3.90

You can solve the problem by converting cost per can (5 cents ) to dollar ($)

Then multiplying cost per can by the number of cans
