At a sale this week, a suit is being sold for $296.40. This is a 62% discount from the original price. What was the original price?

Rounded: $478.06

Step-by-step explanation:

Set up an equation:

Variable x = original price

62/100 = 296.40/x

Cross multiply

62 × x = 100 × 296.40

62x = 29,640

Divide both sides by 62:

x = 478.064516

Round to nearest cent (hundredths place):

x = 478.06

Check your work (using the rounded estimate will be close to $296.40 but not exact because it is rounded; once you round your answer and it should match):

478.06 × 62%

Convert the percentage into a decimal:

478.06 × 0.62

296.3972

Round to the nearest cent (hundredths place):

296.40

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.
