HELP!!!
Jobisdone [24]

Answer:

16 is the number of quarters and 14 is the number of dimes

Step-by-step explanation:

we know that

1\ dime=\$0.10

1\ quarter=\$0.25

Let

x-----> the number of dimes

y------> the number of quarters

we know that

0.10x+0.25y=5.40 -----> equation A

x+y=30 ----Isolate the variable y

y=30-x -----> equation B

Substitute equation B in equation A

0.10x+0.25(30-x)=5.40      

0.10x+7.5-0.25x=5.40

0.25x-0.10x=7.5-5.40

0.15x=2.1

x=14\ dimes

Find the value of y

y=30-x

y=30-14=16\ quarters

therefore

16 is the number of quarters and 14 is the number of dimes
