Susan and her sister ella are making baby blankets to sell at a boutique. Susan has already completed 8 blankets and can finish
Amiraneli [1.4K]

Answer:

It will take 1 day.

Each women will make 17 blankets

Step-by-step explanation:

We can model the number of blankets of Susan and Ella as linear equations:

Susan: B = 8 + 9*t

Where B is the number of blankets and t is the time in days.

For Ella, we have:

B = 10 + 7*t

To find when they will have made the same number of blankets, we just need to equate the value of B from one equation to the value of B from the other, and then we find the value of t:

8 + 9*t = 10 + 7*t

2*t = 2

t = 1 day

After 1 day they will have made the same number of blankets.

This number of blankets is:

B = 8 + 9*1 = 8 + 9 = 17 blankets

a landscaping company needs 160 gallons of 40% fertilize the shrubs in an office park. They have in stock 50% fertilizer and 30%
Novay_Z [31]

Let

x--------> volume of 50​% fertilizer

y--------> volume of 30% fertilizer

we know that

x+y=160-----> x=160-y-----> equation 1

x*0.5+y*0.3=160*0.4-----> equation 2

substitute equation 1 in equation 2

[160-y]*0.5+0.3*y=63.8----> 77-0.35*y+0.25*y=63.8

0.10*y=13.2------> y=13.2/0.10----> y=132 gal

x=220-y----> x=220-132----> x=88 gal

the answer is

88 gal of 50​% fertilizer

132 gal 30​% fertilizer
