Question

Raisins were $700 for a measure, where as plums cost $900 a measure. David and Bruce

bought 50 measures and spent $41,000. How many measures of raisins did they
buy

Answer 1

20 measures of raisins

Explanation:

700 r + 900 p = 41000 ...... (1)

r + p = 50 ⇒ p = 50 - r ....... (2)

(2) ------> (1)

700 r + 900( 50 - r ) = 41 000

700 r - 900 r = 41000 - 45000

- 200 r = - 4000

r = 20 measures
