she ran 15 miles in the first month and 15 in the second but because it doubled in the third month she ran 30 miles. 15+15+30=60 miles total
Answer:
- 1/4
Step-by-step explanation:
He spent $8.14 on the apples in total. Multiple 2.20 and 2.5 to get 5.5 and then multiply 2.20 by 1.2 to get 2.64. Add up 5.5 and 2.64 to get 8.14
The ratio of $2 to $5 is 3: 1
3x$2 + 1x$5 = $11
A set of 3 $2 and 1 $5 gives you $11.
Assumed all 160 coins are $1
Total value = $100
Difference in the value = $300 - $100 = $200
Difference in the $1 and the set of $2 and $5 = $11 - $1 = $10
Number of set of $2 and $5 = $200 ÷ $10 = 20
Calculate the number of $2 and $5 in the 20 sets:
Number of $2 = 3 x 20 = 60
Number of $5 = 1 x 20 = 20
Number of $1 = 160 - 60 - 20 = 80
Answer: There are 80 $1, 60 $2 and 20 $5.
