3 1/10

Step-by-step explanation:

what i think

4/5+1/4 +1/4+3/5= 1.9

Exact form: 19/10

Decimal form:1.9

Mixed number form: 1  9/10

so out of the whole week he goes 3 times so then:

4/5+1/4 +1/4+3/5 x 3= 3.1

Exact form:31/10

Decimal form: 3.1

Mixed number form: 3 1/10

step-by-step explanation:

well if you round, things become much more simple. round 5.95 to 6, 4.25 to 4, and 1.05 to 1. now, add 6+4+1 and that would equal 11. so the items together would equal to about $11.
