1) In a dozen, there are 12. Since there are 5 dozen, you would multiply 12 by 5, which is 60. So 5 dozen oranges would cost $60. 2) For this, I'm guessing you need a ratio. So, 2 : 5 for white: blue. When can put that down to 1 white. 1: 2.5. The question (I'm unsure of) is asking ?: 8.5. 8.5÷ 2.5 = 3.4. So you'll multiply the white side as well, 1×3.4=3.4. So 3.4. 3) You need to find what one juice box would cost. So since there were 12 in the pack, you divide the cost by 12. 5.40÷12= .45 Now they are asking for an eighteen pack, so multiply what one would cost by 18. .45×18= 8.1 It would cost $8.10.
