luda_lava [24]

The total amount of Maureen savings is $ 69

<em><u>Solution:</u></em>

Given that Maureen spent $ 48 on books. That is 70 % of her savings

To find: Total amount of Maureen savings

From given statement, 70 % of her savings is spent on books

Let "x" be the total amount of Maureen savings

Therefore,

70 % of total amount = $ 48

70 % of x = 48

Here "of" represents multiplication or product

70 \% \times x = 48\\\\\frac{70}{100} \times x = 48\\\\0.7x = 48\\\\x = \frac{48}{0.7}\\\\x = 68.57 \approx 69

Thus total amount of Maureen savings is $ 69

3x+2y=11<br> y=5x-1<br><br> SUBSTITUTION <br><br> WORTH 10 POINTS
cupoosta [38]
X=1 and y=4. first I did 
3x+2y=11
y=5x-1
and 3x+2(5x-1)=11
=3x+10x-2=11
=13x-2=11
cancel 2 out
13x=13
x=1. then simply add x in the original y equation,
y=5x-1
y=5(1)-1
y=5-1
y=4.
check your work
3(1)+2(4)=11
4=5(1)-1 
again X=1 AND Y=4 
Hope this helped
