Answer:
Cost of five blouses = $145
Step-by-step explanation:
Let
x = cost of blouse
y = cost of skirt
15x + 2y = 505 (1)
5x + 2y = 215 (2)
Subtract (2) from (1) to eliminate y
15x - 5x = 505 - 215
10x = 290
x = 290/10
x = 29
Substitute x = 29 into (2)
5x + 2y = 215 (2)
5(29) + 2y = 215
145 + 2y = 215
2y = 215 - 145
2y = 70
y = 70/2
y = 35
x = cost of blouse = $29
y = cost of skirt = $35
How much do 5 such blouses cost?
cost of a blouse = $29
Cost of five blouses = $29 × 5
= $145
Cost of five blouses = $145

Answer:
3 1/3 hours
Step-by-step explanation:
First we need to find how much she gets paid per hour. We can find this by diving the pay by the hours worked. Let x equal the pay per hour.
90/5=x
We can simplify the fraction by diving both the numerator and denominator by 5
(90/5)(5/5)=x
Do the division
18/1=x
Gianna gets paid 18 dollars per hour.
Now to find how much she needs to work we can divide the money she wants by the pay she gets per hour. Let y be the number of hours she needs to work.
60/18=y
turn into a mixed number
3 1/3=y
She would need to work 3 1/3 hours to make $60
