Question

for comic relief stamford green school are taking part in a "bake off".parents are invited to come to buy cakes.150 parents attend:70% donate £1 for their cake and the rest donate £2 for their cake.how much money is donated in total?​

Answer 1

£195 is donated in total.

Step-by-step explanation:

Given,

Number of parents who attended bake off = 150

Parents who donated £1 = 70%

Parents who donated £2 = (100-70)% =  30%

Number of parents who donated £1 = $\frac{70}{100}*150=0.7*150=105$

Therefore,

Amount donated by 105 parents = 105*1 = £105

Number of parents who donated £2 = $\frac{30}{100}*150=0.3*150=45$

Amount donated by 45 parents = 45*2 = £90

Total amount donated = £105+£90 = £195

£195 is donated in total.
