Answer:

an apple costs 0.24 and a pear costs 0.28

Step-by-step explanation:

3a + 4p = 1.84 3a + 4p = 1.84

-5a + 2p = 1.76 m(-2) -10a - 4p = -3.52

3a + 4p = 1.84

+ -10a - 4p = -3.52

-7a = -1.68

a = -1.68/-7

a = 0.24

3a + 4p = 1.84

3(0.24) + 4p = 1.84

0.72 + 4p = 1.84

4p = 1.84 - 0.72

4p = 1.12

p = 0.28
