Lexi bought 1 and 2/5 pounds of green grapes and 2 and 3/10 pounds of red grapes grapes are $2.99 a pound did Lexi spend more or
Anika [276]

Amount of green grapes bought = 1\frac{2}{5}=\frac{7}{5} pounds

Amount of red grapes = 2\frac{3}{10}=\frac{23}{10} pounds

Let us assume that both the grapes have same price per pound.

Total quantity of grapes = \frac{7}{5}+\frac{23}{10}

=\frac{14+23}{10}=\frac{37}{10} = 3.7 pounds

Price of 1 pound of grapes = $2.99

So price of 3.7 pounds = 2.99\times3.7 =11.063

Price is $11.063

Hence, Lexi spent less than $12.

lara [203]

Answer:  School Y has 4 points and School X has 12 points.

Explanation:

Let the number of points School Y has be x

Let the number of points School X has be 3x

According to question, we get

3x-x=8\\\\2x=8\\\\x=\frac{8}{2}\\\\x=4

So, the number of point School Y has 4.

and number of points School X has

3x=3\times 4=12

Hence, School Y has 4 points and School X has 12 points.
