The amount John have left after purchase is $10.8.
<h3 /><h3>Amount John have left</h3>
John earned $45.90 during the summer break.
He used 1 / 6 of the money to buy trading card. Then he used the following amount to buy the trading card.
Then, he used 3/5 of the remaining amount to buy a sketchbook, and also spends $4.50. Therefore, the total he spends can be computed as follows:
- 3 / 5 × (45.90 - 7.65) + 4.50 = 22.95 + 4.50 = $27.45
So, He spent
- $7.65 on trading cards
- $22.95 on sketch book
- $4.50 on comic book.
The amount he has left = 45.90 - 7.65 - 22.95 - 4.50 = $10.8

Answer:18
Step-by-step explanation:2−2+22−4=9
18≠9
the ratio of the number of kids is 4:7
that means for every 7 kids we have 4 adults
7 kids ---- 4 adults
the difference is 3
we dived the difference of the kids between the difference of the ratio
150/3 = 50
the number we obtained must be multiply by the ratio of each part
7(50) = 350 number of kids
4(50)=200 number of adults
there are 200 adults at the fun fair
I would set up a proportion:

The proportion basically says, "if there are 5 kids meals for every 4 adult meals, that means 20 kids meals would mean x adult meals." Just cross multiply and then solve for x:

That means there are 20 kids meals sold and 16 adult meals sold, so the result is:
36 meals in total.
