At the supermarket, a bottle of shower foam had a mass of 1.4 kg while a bottle of shampoo had a mass of 1.6 kg. miko bought supplies for half a year and they had a mass of 10.4 kg. she purchased one more bottle of shower foam than shampoo. how many bottles of shower foam did she buy?
Answers: 1
Miko bought 4 shower foams
Step-by-step explanation:
If Miko bought 1 more shower foam, then:
10.4 kg - 1.4 kg = 9 kg
To find the number of items he bought:
1.4 kg + 1.6 kg = 3 kg
9 kg ÷ 3 kg = 3
If he bought 1 more shower foam:
3 + 1 = 4
To check:
4 × 1.4 kg = 5.6 kg
3 × 1.6 kg = 4.8 kg
5.6 kg + 4.8 kg = 10.4 kg
10.35 because 1. 15 x 9 the answer is 10.35
