Answer:

50 = 16 + 7w

amount to save each week for 3 weeks = $11.33

Step-by-step explanation:

Cost of pet iguana = $50

Amount you have = $16

Savings per week = $7

Number of weeks = w

Equation:

50 = 16 + 7w

To find w

50 - 16 = 7w

34 = 7w

w = 34/7

w = 4.86

Approximately w = 5 weeks to the nearest whole week

if you want to buy the iguana in

three weeks

Let x = amount to save each week for 3 weeks

50 = 16 + 3x

50 - 16 = 3x

34 = 3x

x = 34/3

x = 11.33

amount to save each week for 3 weeks = $11.33
