Mylar balloons cost $1.25 each l, and latex balloons cost $0.75 each. what equations can be used to find the number of each type of balloon in a bunch of 18 balloons that costs $19? a)1.25m+0.751=18 b)m+1=18; 1.25m= 0.751 c)1.25m-m=18; 0.751-1=19 d)m+1=18; 1.25m+0.751=19

The equations which can be used from the options given are :

(m + l) = 18

($1.25l + $0.75m) = $19

Cost per mylar balloon, m = $1.25

Cost per latex balloon, l = $0.75

Number of balloons in bunch = 18

Cost of bunch = $19

The cost can be expressed as :

(unit cost of each Ballon × number of each Ballon in a bunch) = total cost of bunch

($1.25l + $0.75m) = $19

Since the total Number of balloons in bunch = 18

And only mylar and latex balloons are present in the bunch ;

Then ;

(Number of mylar+number of latex) balloons = 18

(m + l) = 18

D)

Step-by-step explanation:

Let 'm' represents the number of Mylar balloons  and 'l' represents the number of latex balloons.

Given : Mylar balloons cost $1.25 each l, and latex balloons cost $0.75 each.

i.e. cost of m Mylar balloons in dollars = 1.25 m

i.e. cost of l Latex balloons in dollars = 0.75 l

Then, the equations can be used to find the number of each type of balloon in a bunch of 18 balloons that costs $19 will be :-

Hence, the correct answer is Option D.

only 10/60 isn't equivalent
