[Question]Blake bought 4 lollipops and 6 packs of chocolate. If each lollipop costs $2 and a pack of chocolate costs the same as four lollipops, how much change will Blake get back if he gave the cashier 6 $10 bills?
[Answer]Four pieces of lollipop cost $2x 4 = $8. A pack of chocolate costs $8 so 6 packs cost $8 x 6 = $48. The total amount that she needs to pay is $8 + $48 = $56. Blake gave the cashier $10 x 6 = $60. So, her change is $60 - $56 = $4. The answer is 4.
Q: Rene has three times as many dolls as her sister, while her sister has two more dolls than their grandmother. If their grandmother has 50 dolls, how many dolls do they have altogether?
A: If the grandmother has 50 dolls, Rene's sister, who has 2 more dolls than their grandmother, has 50 + 2 = 52 dolls. Together, Rene's sister and the grandmother have 52 + 50 = 102 dolls. Since Rene has three times as many dolls as her sister, she has 52 * 3 = 156 dolls. Altogether, they have 156 + 102 = 258 dolls. The answer is 258.
