Linear equation is the equation in which the highest power of the variable is one. The second equation for the given problem is.
[tex]0.75d+1.25g=21[/tex]
Thus the option 3 is the correct option.
Given information-
Mary used Delicious (d) and Golden Delicious (g) apples to make homemade applesauce.
Delicious apples are $0. 75 each.
Golden Delicious apples are $1. 25 each.
Total money spent by Mary is $21. 00 on 22 apples.
Linear equation is the equation in which the highest power of the variable is one.
Let [tex]d[/tex] is the delicious apples and [tex]g[/tex] is the golden delicious apple. As the number of apple bought by the Mary is 22. Thus,
[tex]d+g=22\;\;\;\;\;\;\;\;\;\;\;....1[/tex]
Let the above equation is the equation number 1. For the second equation the conditions of the problem should be used. As Delicious apples costs $0. 75 each and Golden Delicious apples costs $1. 25 each. The total money spent by Mary is $21. 00. Thus,
[tex]0.75d+1.25g=21[/tex]
Hence the second equation for the given problem is.
[tex]0.75d+1.25g=21[/tex]
Thus the option 3 is the correct option.
