Natalie bought some fruits. She spent $13 more than
23 of her money on some peaches. She then spent $9 more than 20% of the remaining money on some guavas. Given that she had $27 left,
- How much did Natalie have at first?
- How many kilograms of guavas did she buy if they cost $2 per kg?
(a)
100% - 20% = 80%
80% of remaining money
= 27 + 9
= 36
1% of remaining money
= 36 ÷ 80
= 0.45
100% of remaining money
= 100 x 0.45
= 45
13 of total money
= 45 + 13
= $58
33 of total money
= 3 x 58
= $174
Amount that Natalie had at first = $174
(b)
20% of the remaining money
= 45 x 20%
= 45 x
20100 = $9
Amount spent on guavas
= 9 + 9
= $18
Weight of guavas bought
= 18 ÷ 2
= 9 kg
Answer(s): (a) $174; (b) 9 kg
