Goryan [66]

Answer:

since Sonia saved 45$ in 5 weeks and 70$ in 10 weeks. we are to find the amount she saved up in x weeks.

let's make the amount y

so x= y

5 = 45 cross multiplying the values

we then have 45x= 5y

y= 7x

x=y

10=70

10x = 70y

y= 7x = y=5x+ 20, y = 20x+5

Jessica has 48 coins, some of them are nickels and some are dimes. How many of each does she have if she has $3.25 total? 69 POI

Mrrafil [7]

<u>Answer:</u>

Nickels = 44.6

Dimes = 3.4

<u>Step-by-step explanation:</u>

We know that Jessica has 48 coins of which some are nickels and some are dimes so we can write it as:

n = amount of nickels

d = amount of dimes

$n+d=48$ --- (1)

We are to find the number of nickels and dimes if their total worth is $3.25.

Since a dime is worth 10¢ and a nickel is 5¢, so it should be:

$0.05n + 0.3d = 3.25$ --- (2)

From (1):

$n=48-d$

Substituting this value of $n$ in (2) to get:

$0.05(48-d) + 0.3d = 3.25$

$2.4-0.05d+0.3d=3.25$

$2.4+0.25d=3.25$

$0.25d=0.85$

$d=3.4$

Finding $n$ by substituting the value of $d$ :

$n=48-d$

$n=48-3.4$

$n=44.6$
