Answer:
148
Step-by-step explanation:
5 times 29.6
50 girls attended the trip. ( 80 boy + 50 girls = 130 total students) You just multiply both by 10.
First solve the total number of paper sold, so the total packs of paper sold is equal to 324 / 0.40 = 810 packs of paper sold
% blu paper = ( 81 / 810) x 100 = 10 %
% yellow paper = ( 243 / 810 ) x 100 = 30 %
% pink paper = ( 162 / 810 ) x 100 = 20 %
33/50
=66/100
=<u>0.66 as a decimal</u>
