Question

A teacher pays for x binders with a $20.00 bill and receives $2.30 in change. If each binder costs $5.90, which statement is true?

a.The equation 2.30x+5.90=20 can be used to find x, and the teacher buys 1 binder.

b.The equation 2.30x+5.90=20 can be used to find x, and the teacher buys 3​ binders.

c.The equation 5.90x+2.30=20 can be used to find x, and the teacher buys 1​ binder.

d.The equation 5.90x+2.30=20 can be used to find x, and the teacher buys 3​ binders.

Answer 1

equation c is true i.e x=3binders

Explanation:

5.90x +2.3=20

5.9x=20-2.3

5.9x=17.7

x=17.7/5.9

x=3binders
