10-101.
Calculate how much Linnea spent.
If something is 30% off, that means you pay 70%.
10% of $70 is $7
70% = 7(10%)
70% of $70 = 7($7) = $49
Linnea bought her coat for $49.
If something is 40% off, that means you pay 60%.
10% of $80 is $8
60% = 6(10%)
60% of $80 = 6($8) = $48
Linnea bought her shoes for $48.
Linnea spent $48 + $49 = $90. See if you can use the same method to find out how much money Teagan spent.
