Answer:
4/21 tablespoons of vanilla
Step-by-step explanation:
<u>Let's have the ratios:</u>
- 2/3 tablespoons of vanilla per 3 1/2 dozen cookies
- x tablespoons of vanilla per 1 dozen of cookies
<u>It is solved by cross multiplication as:</u>
- 2/3 × 1 = 3 1/2 × x
- 2/3 = 7/2x
- x = 2/3 ÷ 7/2
- x = 2/3 × 2/7
- x = 4/21
4/21 tablespoons of vanilla needed for 1 dozen of cookies
Answer:
x=3
Step-by-step explanation:
simplify first
4-1=3
X+3=6
next you want to get x by itself
X+3-3=6-3
what you do to one side you must do to the other
X=3
Answer:
The mean amount spent = £14.80
The modal product is hoodies.
Step-by-step explanation:
Here
25 T shirts each costing £10 were purchased
Amount spent on T shirts = 25 × 10 = £250
30 key ring of £5 were purchased
Amount spent on key ring = 30 × 5 = £150
40 Hoodies for £25 each
Amount spent on Hoodies = 40 × 25 =£1000
30 CD's for £15 each
Amount spent on CD's = 30 ×15 = £450
Total amount spent = 250 +150 + 1000 + 450 = £1850
Total items purchased = 25 + 30 + 40 + 30 = 125
Mean amount spent =
The modal product is Hoodies as the maximum number of hoodies were purchased.
Perhaps it is 60, 600? I'm not 100%
