Luke saves 10p coins and 20p coins he has 3 times as many 10p coins as 20p coins a total of 17 pounds how 10p coins does he have ?

10p coins does he have 102

Step-by-step explanation:

given data

saves=  10p coins and 20p coins

total = 17 pounds

to find out

how 10p coins does he have

solution

we consider here no of  20p coin = x

so equation will be here

3 ×  10 x  +20 x = 1700

30 x + 20 x = 1700

x = 34

so that

10p coins    = 3 time × 34  = 102    

20p coins    =  34

so that 10p coins does he have 102

I'm not sure how euros work but I'm almost certain there are 18 20p coins
