For letter b:

First times 5 on both sides to get rid of the denominator of 5

5 * y
— = 4 * 5
5

Then the answer is

y = 20

For letter c:

First move constants on one side, variables on the other

2g = 17 - 8

Then collect like terms:

2g = 9

Then divide both sides which would equal:

g = 9/2

fenix001 [56]

Answer:

Market price of set = 25.14

Step-by-step explanation:

Given:

Discount percentage = 20%

Service charge = 10%

GST = 7%

Amount pays = 23.54

FInd:

Market price of set

Computation:

Assume;

Market price of set = a

Market price of set after discount = a(1-20%)

Market price of set after discount = 0.80a

Market price of set after discount + (Market price of set after discount)(Service charge) + (Market price of set after discount)(GST) = Amount pays

0.80a + (0.80a)(10%) + (0.80a)(7%) = 23.54

0.80a + 0.08a + 0.056a = 23.54

0.936a = 23.54

a = 25.14

Market price of set = 25.14
