Question

Six apples cost as much as four pears. Each pear costs $4 more than each Apple. What is the cost of one pear?

Answer 1

6A = 4P

A = 4/6P = 1/3P

P = A + 4

Substitute P/3 for A in the third equation and solve for P.

Answer 2

Or you could try it this way.

P-4 = A

6A = 4P

Substitute P-4 for A in the second equation and solve for P.

However, something seems askew here. Typos?

Answer 3

Each pear costs $4 more than each Apple ---
p = a + 4

Now , that's some expensive fruit !!

6a = 4p
6a = 4(a+4)
6a = 4a + 16
2a = 16
a = 8 , then p = 12

An apple costs $4 and a pear costs $12
