You mix 2/5 cup of red paint for every 1/4 cup of blue paint to make 1 5/8 gallons of purple paint. How much red paint and blue paint do you use

Answers

Answer=16 cups of red and 10 cups of blue

2/5=8/20=32/80
1/4=5/20=20/80
1 5/8gallons=26cups

32/80+20/80=52/80

26=x(52/80)
divide both sides by (52/80)
40=x
In short, you multiply the mixture by 40 , so...

40*2/5=16cups of red
40*1/4=10cups of blue

A $220 tablet is on sale at half price for $110. You have a coupon for 20% off the sale price. If you use your coupon to buy the tablet, what percent of the original price will you pay?

Answers

ok so $220 is the original price
$110 is the sale price
20% is applicable for the sale price

$110×0.2 (20%= $(20)/(100)$ = 0.2)
= $22

Original price × $(n)/(100)$ = 22
220 × $(n)/(100)$ = 22
$(n)/(100)$ = 0.1
n = 100×0.1
n=10%
We pay 10% of the original price.
Check: 220 × 0.1 (10%= $(10)/(100)$ = 0.1)
=$22
