Question

A pack of 39 balloons and few extra similar balloons were bought for $\$$7.52. If the cost of each ballon is $\$$0.16, then how many extra ballons can be bought?

• A. 6
• B. 8
• C. 10
• D. 11

Answer 1

The correct option is B 8

Given:
Total budget = $\$$7.52
Price per balloon = $\$$0.16
Let the extra ballons bought = $x$

So,
Cost of one balloon × (39 + Extra balloons) = Total budget

0.16 x (39 + $x$) = 7.52

$\frac{0.16}{0.16}$(39 + $x$)= $\frac{7.52}{0.16}$

(39 + $x$) = 47
$x$ = 47-39
$x$ = 8

Therefore,
Number of extra balloons = 8
