Mr Yang’s son has a total of twenty-one $1 and $2 coins in his money box. When he counts his money, he finds that its total valu
irina [24]

Hello!

To solve this, first assume all the coins are $1. Then, find the value that would have. 1 * 21 = $21.

Now, see how far away from $30 we are. 30 - 21 = 9. Therefore, we need an increase by $9.

For each coin changed from a $1 to a $2, how much of an increase is there? $1. Therefore, change 9 coins to $2 coins to have an increase of $9. If he has 9 $2 coins, he'll have 21 - 9 $1 coins, or 12.

Therefore, your final answer is 12 $1 coins and 9 $2 coins.

Hope this helps!

The ages of john and carl add up to 28 years total. John is 20 years older than carl. How many years old is carl?
natima [27]

The correct answer would be that Carl is 4 years old. If John is 20 years older than Carl, that would make him 24. 24 + 4 = 28 years. Therefore, Carl must be 4 years old.

(100 points) find the cost of each treat
Anna71 [15]

Answer:

icecream = $2.99

donut = $1.19

creamcake = $4.99

Step-by-step explanation:

The picture shows $7.17 for 2 x ice-cream and 1 donut

We are given 3 cream cakes that total 14.97 we divide by 3 = 4.99

9.17- 4.99=4.18

=5.37-4.18 =1.19

we can then fill out the boxes.

1.19 +1.19 = 2.38 = 5.37-2.38= £2.99

2.99 +2.99 +1.19 = $7.17

We can see total first two rows = $12.56

2.99+2.99+2.99 +1.19 +1.19+1.19 = $12.56
