Answer:
pen costs twice as much as a pencil. The total cost of 1 pen and 1 pencil is $2.10. If p represents the cost of 1 pencil, which equation could you use to find p ?
2p + p = 2.10 --> p = 0.7
Answer : The equation could you use to find p is, [tex]2p+p=2.10[/tex]
Step-by-step explanation :
Let the cost of 1 pen be, 'x'
and the cost of 1 pencil is, 'p'
As we are given that total cost of 1 pen and 1 pencil is $2.10. The equation will be:
[tex]x+p=2.10[/tex] ............(1)
And we have also given that the pen costs twice as much as a pencil. The equation will be:
[tex]x=2p[/tex] ............(2)
Now put the equation 2 in equation 1, we get:
[tex]x+p=2.10[/tex]
[tex]2p+p=2.10[/tex]
Thus, the equation could you use to find p is, [tex]2p+p=2.10[/tex]
