The total cost of the hip-hop classes is 2 * $10 = $

<<2*10=20>>20 The total cost of the ballet classes is 2 * $12 = $<<2*12=24>>24 The total cost of the jazz class is 1 * $8 = $<<1*8=8>>8 The total cost of all of Lucia’s dance classes in one week is $20 + $24 + $8 = $<<20+24+8=52>>52 #### 52 Josh went to the shopping center. He bought 9 films and 4 books. He also bought 6 CDs. Each film cost $5, each book cost $4 and each CD cost $3. How much did Josh spend in all? The cost of the films is 9 × $5 = $<<9*5=45>>45. The cost of the books is 4 × $4 = $<<4*4=16>>16. The cost of the CDs is 6 × $3 = $<<6*3=18>>18. Josh spent $45 + $16 + $18 = $<<45+16+18=79>>79 in total. #### 79 Marnie makes bead bracelets. She bought 5 bags of 50 beads and 2 bags of 100 beads. If 50 beads are used to make one bracelet, how many bracelets will Marnie be able to make out of the beads she bought? Marnie bought 50 x 5 = <<50*5=250>>250 beads from the 5 bags of 50 beads. She also bought 100 x 2 = <<100*2=200>>200 beads from the 2 bags of 100 beads. She has a total of 250 + 200 = <<250+200=450>>450 beads. Hence, she will be able to make 450/50 = <<450/50=9>>9 bracelets. #### 9 Danai is decorating her house for Halloween. She puts 12 plastic skulls all around the house. She has 4 broomsticks, 1 for each side of the front and back doors to the house. She puts up 12 spiderwebs around various areas of the house. Danai puts twice as many pumpkins around the house as she put spiderwebs. She also places a large cauldron on the dining room table. If Danai has the budget left to buy 20 more decorations and has 10 left to put up, how many decorations will she put up in all? Danai places 12 skulls + 4 broomsticks + 12 spiderwebs + 1 cauldron = <<12+4+12+1=29>>29 decorations. She also puts up twice as many pumpkins around the house as she put spiderwebs, 12 x 2 = <<12*2=24>>24 pumpkins. Danai will also add 20 + 10 decorations to the 29 + 24 decorations already up = 83 total decorations Danai will put up. #### 83 Emilia needs 42 cartons of berries to make a berry cobbler.

If he works 4 times a week, how many vegetables can he chop? Conor can chop 12 x 4 = <<12*4=48>>48 eggplants a week. He can chop 9 x 4 = <<9*4=36>>36 carrots a week. He can chop 8 x 4 = <<8*4=32>>32 potatoes a week. Therefore, Conor can chop 48 + 36 + 32 = <<48+36+32=116>>116 vegetables a week. #### 116 Alice and Bob are each given $2000 to invest.
