Question

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 less than $12 on grapes

Answer 1

Less.

Step-by-step explanation: If you multiple 1 2/5 by $2.99 you would get about $4.19. If you multiple 2 3/10 by $2.99 you would get about $6.88. If you add those together, you would get $11.07, which is less than $12.

Answer 2

Amount of green grapes bought =
`1(2)/(5)=(7)/(5)` pounds

Amount of red grapes =
`2(3)/(10)=(23)/(10)` pounds

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

Total quantity of grapes =
`(7)/(5)+(23)/(10)`

=
`(14+23)/(10)=(37)/(10)` = 3.7 pounds

Price of 1 pound of grapes = $2.99

So price of 3.7 pounds =
`2.99*3.7` =11.063

Price is $11.063

Hence, Lexi spent less than $12.
