A bottle of malt costs three times as much as a bottle of Mirinda. If 5 bottles of malt and 4 bottles of Mirinda cost N380.00 altogether, how much does a bottle of malt cost?
N90.00
N80.000
N60,000
N40,000
N20,000
Correct answer is C
let one bottle of mirinda cost = #x, a bottle of malt will cost #3x
4 bottles of mirinda will cost = #4x, then 5 bottles of malt cost = #15x
total cost = 4x + 15x = 380
x = 380/19 = 20, therefore a bottle of mirinda cost = #20 then a bottle of mirinda will cost 3 x 20 = #60.00
