Dmitriy789 [7]
N=3p and d=p-2  we are also told that:

p+n+d=110 using n and d from above we get:

p+3p+p-2=110

5p-2=110

5p=112

p=112/5

Which is not an integer...are we sure there is no typo in the question...

There are 3 times as many nickels as pennies

There are pennies-2 dimes 

And the total is $1.10

Just checking, because something is off...

Barbara sells iced tea for $1. 49 per bottle and water for $1. 25 per bottle. She wrote an equation to find the number of bottle
Sedbober [7]

The correct option is The Barbara equation did not consider the number of bottles of water.

Given,

The selling price of iced tea is $1.49 per bottle.

The selling price of water is $1.25 per bottle.

Equation written by the Barbara,

1.25x+1.49=100

Here in this question Barbara multiply the selling price of bottle with the number of bottle using the coefficient x, But she did not use any coefficient for the bottle of water. The correct equation is,

1.25x+1.49y=100

where<em> y </em>is the number of water bottle sold to earn the profit of $100.

Hence the correct option is the Barbara equation did not consider the number of bottles of water.
